The lodge pole appear to do well in silty glacial till soils. The glacial till is very dense and hard and has very low rates of permeability. The upper soil above the unweathered till is only about 1 to 2 feet thick. Hence, the upper soil layer becomes saturated in the winter. Lopez and Shaw Islands are within the rain shadow of the Olympic Mountains so the total rainfall results in the till becoming essentially desiccated in the summer. Another climate factor is the San Juan Islands area subject to periodic very cold temperatures associated with the Arctic outflow of air from the Fraser River to the northeast. The combination of wet winter ground, dry ground in the summer and high very cold wind is a good match for lodge pole. </p><p>During a recent venture I came across lodge pole pines growing within a logging road on the steep upper northeast slope of Mount Constitution on Orcas Island. The logging road was beginning to get colonized by brush and trees. </p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEitKQQm4qc0hApN63Dfj5hgKCgCu63hzJybWNyK_0VkYifaYt-NBEQQcTdKAksp5jqDBGrsZ8xk7NaMuzJlkM6s04SVs7-QcxdfG4lZ2B5s0TaW_XWZc3COVV0sGC1zP1o8DQtL7hyphenhyphenk-sWFzA6PRbU_x2JU5YaMelz63LZ4o3duykDtNif1qf43XZhMXm3Q/s5472/IMG_1337.JPG" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3648" data-original-width="5472" height="266" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEitKQQm4qc0hApN63Dfj5hgKCgCu63hzJybWNyK_0VkYifaYt-NBEQQcTdKAksp5jqDBGrsZ8xk7NaMuzJlkM6s04SVs7-QcxdfG4lZ2B5s0TaW_XWZc3COVV0sGC1zP1o8DQtL7hyphenhyphenk-sWFzA6PRbU_x2JU5YaMelz63LZ4o3duykDtNif1qf43XZhMXm3Q/w400-h266/IMG_1337.JPG" width="400" /></a></div><p></p><p>The seedlings on the road were primarily western hemlock and lodge pole pine. There were a few Douglas fir seedlings, but they were heavily browsed by deer as was the ocean spray brush. There were couple of Sitka spruce seedlings as well. The dominant tree in most of this forest outside the clear cut is Douglas fir, but western hemlock thrives on this wet shady northeast facing slope and there are numerous clusters of Sitka Spruce in the near vicinity and scattered through this forest area likely due to the cooler temperatures and relatively high rainfall on the upper slopes of Mount Constitution. The lodge pole in this cool wet area appears to be a pioneer tree taking advantage of the wet hard ground of the old road bed. Large area of the upper part of Mount Constitution has stands of lodge pole possible due to the the same combination of wet winter and dry summer conditions but also the upper summit area gets very high wind from all directions and perhaps that and a periodic in the past lightning stikes provided the openings that lodge poles thrive in. </p><p>My home ground on Samish Island on the northern edge of the Skagit River delta is underlain by concrete like glacial till and goes from wet soggy ground to desiccated every year. It is also subject to very high winds. In particular the south and east winds knock trees down regularly in the winter on out portion of the island. Elsewhere on the island it is the north or west wind. </p><p>Given that the seedlings on the road were doomed I took a few lodge pole seedlings and one Sitka spruce seedling home. </p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhJ4YNGK_eV0mTQ947FwWPikf4i5OzxPLqsKMjVOIOH31nFMkJJ3HNuAOn3qTBReWynzxvkyI16N6PlXFARB6jKAPB7K0XznwkHM1RYovUJjm7qAvBwIKaM7OZTWssDRKMia9ypqEka6WVQQDOU9DdQSzmERktbQt_kuE8EA1P9IyTSSrc2rmjNmOy_prEt/s5472/IMG_1363.JPG" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3648" data-original-width="5472" height="266" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhJ4YNGK_eV0mTQ947FwWPikf4i5OzxPLqsKMjVOIOH31nFMkJJ3HNuAOn3qTBReWynzxvkyI16N6PlXFARB6jKAPB7K0XznwkHM1RYovUJjm7qAvBwIKaM7OZTWssDRKMia9ypqEka6WVQQDOU9DdQSzmERktbQt_kuE8EA1P9IyTSSrc2rmjNmOy_prEt/w400-h266/IMG_1363.JPG" width="400" /></a></div><div class="separator" style="clear: both; text-align: center;">Lodge pole seedling in its new home.</div><p>Assessing the forest is not my area of expertise, but I have accumulated a few observations and try to keep learning.

Russell did some of the earliest work on trying to figure out some of the remarkable features of Washington State (<a href="https://pubs.usgs.gov/bul/0108/report.pdf">Russell (1893)</a>, <a href="https://pubs.usgs.gov/wsp/0004/report.pdf" target="_blank">Russell (1897)</a> and <a href="https://books.google.com/books?id=9bbkAAAAMAAJ&printsec=frontcover&source=gbs_ge_summary_r&cad=0#v=onepage&q&f=false" target="_blank">Russell (1900)</a>. He made a significant effort in his writing style to appeal to non geologist readers as well as the technical detail needed for his USGS reports. Russell is referenced several times in a book I recently read, <u>The Great Columbia Plain A Historical Geography 1805-1910</u> by Donald Meinig. I crossed paths with Russel again when doing some research for work I was doing in the Yakima Canyon. </p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgOHdW_hkmfKCkGHNcFtjgxcqb4ROJ-lyEoCxfxCZnDbhNO0WmZgtSfaLzqT4Vlt4GEur03o4gKaot7JpQpJ5cC-_rZD8xg3TSsmjth7HHI2miMbM_fs0ujVImOc7cAmFIEufGNLMFO2hv_hLscuvb5xBGLoohEQScbySXRyrifmyaQYHbRfQEQSFij24Ns/s855/1892.png" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="551" data-original-width="855" height="258" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgOHdW_hkmfKCkGHNcFtjgxcqb4ROJ-lyEoCxfxCZnDbhNO0WmZgtSfaLzqT4Vlt4GEur03o4gKaot7JpQpJ5cC-_rZD8xg3TSsmjth7HHI2miMbM_fs0ujVImOc7cAmFIEufGNLMFO2hv_hLscuvb5xBGLoohEQScbySXRyrifmyaQYHbRfQEQSFij24Ns/w400-h258/1892.png" width="400" /></a></div><div class="separator" style="clear: both; text-align: center;">1892 View of Yakima Canyon from Russell (1893)</div><div class="separator" style="clear: both; text-align: center;">The view is to the north with Rattlesnake Ridge on the distant right side (there is a trail up that ridge).</div><div class="separator" style="clear: both; text-align: center;">The railroad grade is on the west, left, side of the river. </div><div class="separator" style="clear: both; text-align: center;">The picture predates the road that was later built on the east side.</div><div class="separator" style="clear: both; text-align: center;"><br /></div><div class="separator" style="clear: both; text-align: center;"><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg4gimNk8tBkxiE3R-tI4wB-58iW9du6MLQGChAeryHssTZ1CBM22Mjhw7UxS9JNhx_8H3wIJMToJ_U_zFvGVmk0QV17Ds6O6fj7tgN18C0EL2gkFniUbMKFKHZ9yhh5CC7S-vuO-54gMGpt01YQBvYgn694LCdVe9H_3fWcloZIcHPGEXg9GkImqLRozsQ/s5472/IMG_1378.JPG" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3648" data-original-width="5472" height="266" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg4gimNk8tBkxiE3R-tI4wB-58iW9du6MLQGChAeryHssTZ1CBM22Mjhw7UxS9JNhx_8H3wIJMToJ_U_zFvGVmk0QV17Ds6O6fj7tgN18C0EL2gkFniUbMKFKHZ9yhh5CC7S-vuO-54gMGpt01YQBvYgn694LCdVe9H_3fWcloZIcHPGEXg9GkImqLRozsQ/w400-h266/IMG_1378.JPG" width="400" /></a></div>I think the picture in the Russell (1893) report was taken from the basalt outcrop below the top edge of the canyon to the left of the tall pine. <br /> </div><div class="separator" style="clear: both; text-align: left;">Russel (1893) also described the Toppenish Landslide <a href="https://washingtonlandscape.blogspot.com/2019/09/toppenish-ridge-landslide-near-mabton.html" target="_blank">(toppenish-ridge-landslide-near-mabton)</a> as well as the Great Terrace along the Columbia River near Chelan. </div><div class="separator" style="clear: both; text-align: left;"><br /></div><div class="separator" style="clear: both; text-align: left;">Skye Cooley provides an overview of Russell's 1893 paper on central Washington (<a href="https://www.skyecooley.com/single-post/i-s-russell-s-reconnaissance-of-central-washington-1893" target="_blank">i-s-russell-s-reconnaissance-of-central-washington-1893</a>).

The cold periods in western Washington are short. I will say that while the areas subject to Fraser River outflow winds are a bit rough - 50 mph winds when the temperature in the teens and single digit range is not pleasant. </p><p>The north edge of Skagit delta does get cold due to the proximity of the Fraser Canyon winds coming down across Whatcom County and over Bellingham and Samish Bay. The delta is generally a windy place, but Samish Island deflects the north wind such that the south side of the island is cold but not windy. </p><p>Alice Bay, a bay that is separated from Samish Bay by a low peninsula of salt water marsh was completely frozen over. Alice Bay usually completely empties of water during low tides; hence, the shallow water during high tides freezes. </p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgaJDtnFKQemP43mbO1h3feqDuZeE2TJDWIO9AOjqSIyWLK_ZyFXmXcxJIZtcJd5tFsYjOSgZhvCVKES5Ogo5RTpmGh9Q_HPAcJXPUsVtR4PkVTZ6O8klXkWJDDlC8N1yX-OZKqWBCk06M3NIl7RBh2tfLzXqRiLcsYSjuJu0wGnOZ27vChKMRywPeswGBn/s4778/IMG_1377.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3221" data-original-width="4778" height="270" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgaJDtnFKQemP43mbO1h3feqDuZeE2TJDWIO9AOjqSIyWLK_ZyFXmXcxJIZtcJd5tFsYjOSgZhvCVKES5Ogo5RTpmGh9Q_HPAcJXPUsVtR4PkVTZ6O8klXkWJDDlC8N1yX-OZKqWBCk06M3NIl7RBh2tfLzXqRiLcsYSjuJu0wGnOZ27vChKMRywPeswGBn/w400-h270/IMG_1377.JPG" width="400" /></a></div><div class="separator" style="clear: both; text-align: center;">Alice Bay with Scott Point on the near left and Blanchard Mountain behind,</div><div class="separator" style="clear: both; text-align: center;">snowy Anderson Mountain on center left and Lyman Hill the ridge on the center right. </div><div class="separator" style="clear: both; text-align: center;">Note the odd naming of Lyman Hill.

The basalt is Columbia River Basalt Group magma that erupted as huge flood basalts in northeast Oregon and southeast Washington. The lava flows extended down the ancestral route of the Columbia River all the way to the Pacific Ocean about 15 million years ago. </p><p>The basalts along the Oregon Coast were thought to be of local derivation as there are numerous intrusive dikes and sills within the local sedimentary rocks. However, as detailed chemical analysis and age dates of the basalts were obtained it turned out that these north Oregon coast basalt matched the chemistry and the age of the basalt of the Columbia River Basalt Group.

Hence, the dikes and sills of basalt within the soft sediments along north coast of Oregon are not from local volcanic centers but are from lava flows that sank down into the soft sediment intruding or invading the soft sediment mud. </p><p>The haystack rocks and cliff south of Cannon Beach are good sites for observing this phenomenon.</p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhwjqqmSTy3v-wGz0OOqHqTVLbMaAZVKRFvqRWxFeAuj2GidvTQQkarqf1HEYy8AyfN44K6FkvyUOmnb_Or-yV8s9hk17mIyCj1jE5G10QEEAD0BOUPz6onTjZcs5LIitOvJNar3HvMBvsZrbPtcPdfNZ71cIaQ2OkyVItPwucczulmauAdpw5Pa2M6dZZA/s5472/IMG_9211.JPG" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3648" data-original-width="5472" height="266" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhwjqqmSTy3v-wGz0OOqHqTVLbMaAZVKRFvqRWxFeAuj2GidvTQQkarqf1HEYy8AyfN44K6FkvyUOmnb_Or-yV8s9hk17mIyCj1jE5G10QEEAD0BOUPz6onTjZcs5LIitOvJNar3HvMBvsZrbPtcPdfNZ71cIaQ2OkyVItPwucczulmauAdpw5Pa2M6dZZA/w400-h266/IMG_9211.JPG" width="400" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjtMZeFGzJNf7haiNYnJNP4eyWWoK-1BmxFaaAmIsXW6csGCu6p8_OfWLFKr7WWxxWH-r7l-goCFq0keqDrQr4kT9LzCdH8MYxyj45IQQrsq4zF77FynWzAYuaAjCrGQdyIIpeFR-fGQZsd5RUJ1brpbP8qq_DK6vynIou7iYUVTCn0TZjxOIgKRBs9SQro/s5472/IMG_9209.JPG" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3648" data-original-width="5472" height="266" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjtMZeFGzJNf7haiNYnJNP4eyWWoK-1BmxFaaAmIsXW6csGCu6p8_OfWLFKr7WWxxWH-r7l-goCFq0keqDrQr4kT9LzCdH8MYxyj45IQQrsq4zF77FynWzAYuaAjCrGQdyIIpeFR-fGQZsd5RUJ1brpbP8qq_DK6vynIou7iYUVTCn0TZjxOIgKRBs9SQro/w400-h266/IMG_9209.JPG" width="400" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg9WBjbJJt7V5h7RBcw_07aJnHwI1MDNNd_HZV7G4AD-DdUckPc6QO7pt7RZBMcD12tzOYjaF-Kw41XEPoJn1MXPknEgutsaZqHrnHMe2I1Rk8zOZVSwJ4xaA995trqLu6gjSyPzCjBrzLW7llWLpL06kHpk_ObNylvN7qfiljPfB879AVlqkEkOid_4X6f/s5472/IMG_9212.JPG" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3648" data-original-width="5472" height="266" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg9WBjbJJt7V5h7RBcw_07aJnHwI1MDNNd_HZV7G4AD-DdUckPc6QO7pt7RZBMcD12tzOYjaF-Kw41XEPoJn1MXPknEgutsaZqHrnHMe2I1Rk8zOZVSwJ4xaA995trqLu6gjSyPzCjBrzLW7llWLpL06kHpk_ObNylvN7qfiljPfB879AVlqkEkOid_4X6f/w400-h266/IMG_9212.JPG" width="400" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjVd1ZXMkROYH1Xo9a-LwNAqT4sub6EJSA02u0AvqRDn-rjJXSUvVcg_Uc2jHHugT2VL1CeLE9sMpUsWFgkBGDXr6TaRMvh1u6hs_-sUsdpPYopAttgKWuOMu7qxXC-GBPAgqPdWb-8Lcd1uFCAjE6qmPM9OGygROcHFly97WPPlEZ0AF2kOavqzkc6l54C/s5472/IMG_9215.JPG" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3648" data-original-width="5472" height="266" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjVd1ZXMkROYH1Xo9a-LwNAqT4sub6EJSA02u0AvqRDn-rjJXSUvVcg_Uc2jHHugT2VL1CeLE9sMpUsWFgkBGDXr6TaRMvh1u6hs_-sUsdpPYopAttgKWuOMu7qxXC-GBPAgqPdWb-8Lcd1uFCAjE6qmPM9OGygROcHFly97WPPlEZ0AF2kOavqzkc6l54C/w400-h266/IMG_9215.JPG" width="400" /></a></div><br />A challenge is to get to the area at low tide.

King tides are the higher high tides of the year and winter is when the tides are the highest.

However, the tilt of the earth relative to the earth's orbit results in the Washington coast dipping downward into the maximum tide zone during the winter solstice. Hence, our highest astronomical tides take place in the December/January period. </div><div class="separator" style="clear: both; text-align: center;"><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg1C-s5FoixsR6jolVl863r6MOWZLy9KT12Cw5WtyIRkmBYUFQcAPjzEsrUxF2-FFaRb4_vpfw95GE4lOwIIgR9iTAZb_amYacR2lwE2Y4QryPW84n_mxdDQYJ0HFtv9i8rk5WhoU_e9Ti2QiLqsEawLLVQFAY5t4vKiZsrd-5l6tXtsUmRaRQY83qv3P7g/s758/KingTideDeclination.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="492" data-original-width="758" height="260" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg1C-s5FoixsR6jolVl863r6MOWZLy9KT12Cw5WtyIRkmBYUFQcAPjzEsrUxF2-FFaRb4_vpfw95GE4lOwIIgR9iTAZb_amYacR2lwE2Y4QryPW84n_mxdDQYJ0HFtv9i8rk5WhoU_e9Ti2QiLqsEawLLVQFAY5t4vKiZsrd-5l6tXtsUmRaRQY83qv3P7g/w400-h260/KingTideDeclination.png" width="400" /></a></div><div class="separator" style="clear: both; text-align: center;">Declination and tides from Hicks (2006). </div><div><br /></div>In the above figure Washington State is approximately at the C-D line. The result is that when we are at position C we are in the king tide zone. <div><br /></div><div><i><u>Other Factors</u></i></div><div><br /></div><div><b>Storm Surge</b>: The astronomical tide is impacted by meteorological forcing. A deep low pressure system will result in a higher tide level than the astronomical tide. The wind around the deep low pressure also results in water being piled up against the coast depending on the track of the low pressure. The track of a hurricane center is a very important component of the storm surge associated with hurricanes. The low pressure of the hurricane will result in storm surge but so does the wind. Being on the right hand side of an approaching hurricane (from the hurricane's view) can result in huge storm surges.</div><div><br /></div><div>The same issue holds true for the Washington State coast. Deep low pressure systems bring lots of wind that will push and pile water up at different locations depending on the track of the low and the wind fields around the low. The impact of deep low pressure storms and associated wind fields on the inland waters of the Salish Sea is complex due to the shape of the multiple waterways. Yang and others (2019) modeled storm surge in the Salish Sea and provide an estimated maximum storm surge map for the Salish Sea.</div><div><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiJounweLNOtSZFzJijEM3KPDRkvaI7akv97WdKjBpNUAVWkkLR1fSw42WKZeqmET-e419flc0ZIM-ThtxrnZgUMOo8FkSzoNjKOde21giH1h11v-4z4pdWIDWkG3JH3IP401KqhyacDZAvjt1TRzZKgTW7waPb4Dr0GgVfLhiqRZ2IyRN327mwrBTwKV4H/s680/Yangandothers2019MaxStormSurge.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="498" data-original-width="680" height="293" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiJounweLNOtSZFzJijEM3KPDRkvaI7akv97WdKjBpNUAVWkkLR1fSw42WKZeqmET-e419flc0ZIM-ThtxrnZgUMOo8FkSzoNjKOde21giH1h11v-4z4pdWIDWkG3JH3IP401KqhyacDZAvjt1TRzZKgTW7waPb4Dr0GgVfLhiqRZ2IyRN327mwrBTwKV4H/w400-h293/Yangandothers2019MaxStormSurge.png" width="400" /></a></div><div class="separator" style="clear: both; text-align: center;">Figure 12 from Yang and others (2019)</div><div><br /></div>A large storm surge December 27, 2022 resulted in significant shoreline flooding as the storm surge coincided with an already high astronomical high tide event. <div><div class="separator" style="clear: both; text-align: center;"><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg5oEndWxW3_t921KWF_A-sr3d6yuIPxYEoZFwRm2-36sT-Gzx2wlapkWrtAQx3OkaVk0X1s4yZ1uVYvh08AW80Lv_UV6khvqQpi4hF2qopCo8Wj7zcvYwCf9DNma13gAQs6RRaIwrVHBchE8knEpSLc428036sgAUyiwrYOjXhK2h01nLqC7UDha7Yvbhv/s5472/IMG_6246.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3648" data-original-width="5472" height="266" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg5oEndWxW3_t921KWF_A-sr3d6yuIPxYEoZFwRm2-36sT-Gzx2wlapkWrtAQx3OkaVk0X1s4yZ1uVYvh08AW80Lv_UV6khvqQpi4hF2qopCo8Wj7zcvYwCf9DNma13gAQs6RRaIwrVHBchE8knEpSLc428036sgAUyiwrYOjXhK2h01nLqC7UDha7Yvbhv/w400-h266/IMG_6246.JPG" width="400" /></a></div><div class="separator" style="clear: both; text-align: center;">Water overtopping shoreline dike at Alice Bay, Skagit County</div><div class="separator" style="clear: both; text-align: center;">(note center road stripe under water) </div><div class="separator" style="clear: both; text-align: center;"><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgw-Oo5V5mLAjxNuZEWKpj40vEHMBndwVWxWkTnbP8rGOkZ-0h9VSD3jkLFCC6qP54f5v4hED1cnHlttX-9p8yAWgoZdLpHiSmxE1oWmSDkz7i04M4ZZyJFZkZ6UguHDb4Msb1vzLCQXfkHMXJXGbPV9oVfZvaEycdPXhT4C5FNTwqtMdJB9UwsWCtnoT7b/s5472/IMG_6251.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3648" data-original-width="5472" height="266" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgw-Oo5V5mLAjxNuZEWKpj40vEHMBndwVWxWkTnbP8rGOkZ-0h9VSD3jkLFCC6qP54f5v4hED1cnHlttX-9p8yAWgoZdLpHiSmxE1oWmSDkz7i04M4ZZyJFZkZ6UguHDb4Msb1vzLCQXfkHMXJXGbPV9oVfZvaEycdPXhT4C5FNTwqtMdJB9UwsWCtnoT7b/w400-h266/IMG_6251.JPG" width="400" /></a></div><div class="separator" style="clear: both; text-align: center;">Water overtopping shoreline dike at Alice Bay</div><div class="separator" style="clear: both; text-align: center;">(note white fog line road stripe under water)</div><div><br /></div><b>18.61-year lunar nodal cycle</b>: The plane of the orbit of the moon is inclined 5.145° from the equator. The result is that the moon's pull on the tide varies. When the moon is above the equatorial plane the pull is larger. We are currently in a period when the moon is more frequently above the equatorial plane during the king tide period. The result is more frequent tides being extra high this year as well as next and therefore the odds of a very high astronomical tide coinciding with a storm surge are greater this year and next than on average. </div><div><br /></div><div><b>Timing of winter high tides</b></div><div><b><br /></b></div><div>The tides set the waters of the ocean basins into motion. This moving water pushes up or pulls away continents and up into the inlets like such as the Salish Sea. The actual response of the ocean
basins and estuaries to tides is complicated and can lead to some pretty remarkable tides. I recall walking out on a dock in the Bay of Fundy with a 2 year old and being terrified of the potential fall hazard with boats 50 feet below us during low tide. Hicks (2006) provides a good overview of the factors that impact estuary tide levels. <br /><br /></div><div>A peculiar feature of tide interactions in the Salish Sea area I work along most frequently is the lack of low tide during the day light hours of winter. Assessments of shoreline bluffs in mid winter can be complicated by the tides as the plot below shows.</div><div><br /></div><div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg2-s_WYBG8U6Rzjn7-B8iEjrFQBJQb2YoIp_nEOOBZuxl-NWOdnJd9H4zD5TQdnBf_m1qBRzr-dqgT1KtJ7iq4A78pWlIQQm2tw_UZbUmS94lE3A3NxwxcWAveUYpFopKq8K142Q9qO-9Fuf_z__2Oi_3F8zX53OXqGPQqfYvijGg8MlBlMANhyphenhyphenAL4ata8/s1200/noaanosco-opsobserved-wa.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="874" data-original-width="1200" height="291" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg2-s_WYBG8U6Rzjn7-B8iEjrFQBJQb2YoIp_nEOOBZuxl-NWOdnJd9H4zD5TQdnBf_m1qBRzr-dqgT1KtJ7iq4A78pWlIQQm2tw_UZbUmS94lE3A3NxwxcWAveUYpFopKq8K142Q9qO-9Fuf_z__2Oi_3F8zX53OXqGPQqfYvijGg8MlBlMANhyphenhyphenAL4ata8/w400-h291/noaanosco-opsobserved-wa.png" width="400" /></a></div>High tide was at about 8 in the morning, but the low tide at noon is not exactly low with second high tide coming in at 3:15 in the afternoon. The main low tide was really low - a negative tide at around midnight. Clam digging or oyster harvest at night in the winter. <br /><br />I had a bit of hike to reach the shoreline bluff I needed to visit as there was no access down the very steep and high bluff for a few miles in both directions. I know this shore reach well enough that I figured I could make the 8 mile round trip hike with only the need for limited wading where the beach was narrow. With sunset at 4 the best I was going to get was a tide of about 8 feet. Note that there was minimal storm surge and the other plus was it was a calm day with no ocean swell coming in the strait. I started the hike after noon. The deepest wade was only shin deep and the waves were minimal. The water was warmer than the steady rain as the air temperature was 38 degrees. </div><div><div class="separator" style="clear: both; text-align: center;"><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjTLC4d14avg3-vwSfFc28IFiAf2-D5Ql_Oy3f7YcIdC2eebH8C2rpd43Hmia99Zx7mhdux6zN88DIQoDgoWfLT6znjB0-E3-Vxx_Lv01McKk_0U1k6Nf7hzdTwqDlqc-bcmZFS1gJTk48agYrJR0g7elFR3p3OgrbB5Ksbv7nIqBVpw4YfeO1YiEPyvPot/s5472/IMG_0854.JPG" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3648" data-original-width="5472" height="266" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjTLC4d14avg3-vwSfFc28IFiAf2-D5Ql_Oy3f7YcIdC2eebH8C2rpd43Hmia99Zx7mhdux6zN88DIQoDgoWfLT6znjB0-E3-Vxx_Lv01McKk_0U1k6Nf7hzdTwqDlqc-bcmZFS1gJTk48agYrJR0g7elFR3p3OgrbB5Ksbv7nIqBVpw4YfeO1YiEPyvPot/w400-h266/IMG_0854.JPG" width="400" /></a></div><div class="separator" style="clear: both; text-align: center;">House lights atop a high bluff above the Salish Sea</div><p>I took the above picture while heading back from my venture.

I had been making a fair bit of noise smashing through a thicket of dense brush before weaving through some branches to meet this owl. Hawks and larger owls prey on them so being down at a low level in the thicker brush is a safer place. Unlike the barred owl that visited the house, this owl seemed fit and alert.</p>Dan McShanehttp://www.blogger.com/profile/17044037213245602667noreply@blogger.com1tag:blogger.com,1999:blog-9188642669907788257.post-21753711687396039672023-10-09T21:16:00.000-07:002023-10-09T21:16:01.538-07:00Barred Owl Last Visit <p></p><div class="separator" style="clear: both; text-align: left;">This is not a normal thing:</div><div class="separator" style="clear: both; text-align: center;"><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi3S1TsgKLf0GwO1aJh1O7I17gxMnPS_rSC2aMj8RKwrC59OUwx3vYB1g1rVnGUnM0Y4aPeUR7bDNgPESMv-SBVJ1lEtZDZ0KpFJbMDjUnSLwAr7hBaKUkoAH0BZsKTml-CcgL4-CpdRA-dDhtA3eZ49Vq5VnpttAPFGNV4nLnZJNG-oJZzaZhc1ohqF6P-/s5472/IMG_0144.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3648" data-original-width="5472" height="266" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi3S1TsgKLf0GwO1aJh1O7I17gxMnPS_rSC2aMj8RKwrC59OUwx3vYB1g1rVnGUnM0Y4aPeUR7bDNgPESMv-SBVJ1lEtZDZ0KpFJbMDjUnSLwAr7hBaKUkoAH0BZsKTml-CcgL4-CpdRA-dDhtA3eZ49Vq5VnpttAPFGNV4nLnZJNG-oJZzaZhc1ohqF6P-/w400-h266/IMG_0144.JPG" width="400" /></a></div><div class="separator" style="clear: both; text-align: center;">Barred owl on the ground </div><p>The owl did not take flight when approached. I went about various projects after having been away for an extended time and hoped that the owl might recover from whatever was the cause of its ailment. But I was aware that this owl was under some significant distress. Alas, whatever ailed our visitor resulted in the owl dying the next night. </p><p>I find it difficult to spot owls perched in the forest so am uncertain of our very local barred owl population. More often I hear great horned owls and only very occasional will hear a barred. This is the first barred owl I have seen at our house. I have seen great horned owls perched on the same wheel barrow in the picture above. </p><p>Barred owls are relatively new arrivals to Washington State. They have expanded their range from eastern North America to across Canada to the Pacific Northwest. The arrival of barred owls has been one of the causes of the decline of spotted owls. <a href="https://www.pnas.org/doi/full/10.1073/pnas.2102859118" target="_blank">Weins and others (2021)</a> evaluated lethal removal of bared owls on spotted owl survival.</p><p></p>Dan McShanehttp://www.blogger.com/profile/17044037213245602667noreply@blogger.com0tag:blogger.com,1999:blog-9188642669907788257.post-15980450462864941252023-09-30T13:21:00.000-07:002023-09-30T13:21:10.901-07:00Opuntia columbiana<p>While on a field work venture along the Yakima River in central Washington I came across a patch of what I believe to be <i>Opuntia columbia</i>.

<div class="separator" style="clear: both; text-align: left;">I have had several ventures on the steep north slope of Mount Frailey above Lake Cavanaugh in Skagit County. These ventures were to assess alluvial fan hazards which has meant assessing the steep drainages above the alluvial fans. Like much of the Northwest Cascades bedrock exposures are sometimes limited to stream channels. Hence the steep drainages on the north side of Frailey Mountain provided a good opportunity to see the bedrock hiding under the thick forest landscape. The lower slopes of Mount Frailey are underlain by sedimentary rocks called Rocks of Bulson Creek. </div>

The hard conglomerate of the formation forms cliffs and a few nice cascades on the stream Bob and I were exploring. The clasts in the conglomerate are derived from nearby metamorphic rocks of the Eastern Mélange Belt which is well exposed on the slope above this outcrop. The Eastern Mélange Belt consists of Triassic to Jurassic age ocean floor terrane thrust up onto the edge of North America. It is one of several accreted terranes in the Northwest Cascades.</div><div dir="ltr" style="text-align: left;" trbidi="on"><br /></div><div dir="ltr" style="text-align: left;" trbidi="on">The Rocks of Bulson Creek are Oligocene to Eocene and post date the terrane accretion. The Bulson appears to be deposited on the metamorphic rocks (Marcus, 1981) and appears to be a localized sedimentary in a localized basin that formed during the late to post Eocene time likely associated with the Devils Mountain-Darrington Fault (Lovseth, 1975 and Marcus, 1981). In the Lake McMurray area to the east the Bulson has clasts of Eocene to Oligocene volcanic rocks that are of local derivation. </div><div dir="ltr" style="text-align: left;" trbidi="on"> <div class="separator" style="clear: both; text-align: center;"><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEh0e0AEHrtdx1qVIRur6rCoM3z_eLQIjNOFDOQTefJXJN3NFCARKjfM1zuaUeSfZeyAi6rTvHrhkPDk5hqpejEHzws0ftn4THCt1UGsPQ-uTaK3rcsrFAdExvbJFc0eQhWPnUsslkD6eOumRsk_6UOyVLlOdy4XnTWnm2J-oO4k_O56So_o_gORN1qAEA" style="margin-left: 1em; margin-right: 1em;"><img alt="" data-original-height="556" data-original-width="438" height="400" src="https://blogger.googleusercontent.com/img/a/AVvXsEh0e0AEHrtdx1qVIRur6rCoM3z_eLQIjNOFDOQTefJXJN3NFCARKjfM1zuaUeSfZeyAi6rTvHrhkPDk5hqpejEHzws0ftn4THCt1UGsPQ-uTaK3rcsrFAdExvbJFc0eQhWPnUsslkD6eOumRsk_6UOyVLlOdy4XnTWnm2J-oO4k_O56So_o_gORN1qAEA=w315-h400" width="315" /></a></div><div class="separator" style="clear: both; text-align: center;">Distribution of Rocks of Bulson Creek from Marcus (1981)</div><div class="separator" style="clear: both; text-align: center;"><br /></div><div style="text-align: left;">Lovseth (1975) recognized the Bulson as a separate sedimentary unit than the similar looking Chuckanut Formation to the north.

Given the age of the forests around Lake Cavanaugh area, there has been significant logging in the area the past few years. As noted in a previous post <a href="https://washingtonlandscape.blogspot.com/2020/01/blog-post_28.html" target="_blank">(HERE)</a>, the trees that were left are habitat for marbled murrlets and hence some of the forest is protected. And some of the slopes may be precluded from logging due to potential landslides and debris flow hazards. I say 'may' because that can be a geology judgement call clear cut logging has been permitted on active alluvial fan areas. <br /> <p></p>Dan McShanehttp://www.blogger.com/profile/17044037213245602667noreply@blogger.com0tag:blogger.com,1999:blog-9188642669907788257.post-8952949712315052692023-05-06T11:12:00.000-07:002023-05-06T11:12:01.747-07:00Colaptes auratus (Northern Flicker) Duel<p> I was alerted to the nearby presence of a northern flicker by the drumming on a metal gutter.
