Practice for the Coming Cold Spell

The weather folks are indicating a bit of a cold spell arriving via outflow winds down the Fraser Canyon in BC and through Bellingham starting sometime Monday.

 

I got a little cold weather practice this past week as I had some field work in eastern Washington which I combined with Thanksgiving in the old home town of Kennewick. The initial start of my work was cold, but I did have sun.

Winters in the eastern Washington are much drier than western Washington; however, fog does settle in the valleys and after my initial sunny day I had fog the rest of the week.

Mount Baker Glacial Ice Loss

Don Easterbook is worked up by a recent Bellingham Herald article by John Stark on a presentation to the local City Club monthly talk by Michelle Koppes letter-to-weeditors-some-cold-hard-truth-about-our-local-glaciers.html.

I have little interest this time in whack-a-mole with Easterbrook's graphs (see below), but Easterbrook takes issue with a statement Koppes made about our local Mount Baker glaciers,  "Koppes claims that "glaciers on Mt. Baker…..have lost 20 percent of their volume since 1990."  This one is mind-boggling! Keeping in mind that glaciers thicken rapidly upvalley from their terminus, the total amount of ice loss since 1990 can’t be more than a few percent. Other glaciers show the same relationship. How any competent glaciologist could come to such a conclusion is hard to imagine."

Koppes was referencing an ongoing study program that has been taking place on North Cascade Range glaciers including three on Mount Baker over the past for 30 years. Measurements indicate that indeed the loss in ice volume on the three Mount Baker glaciers since 1990 is 15 to 20 percent http://issuu.com/mspelto/docs/mount_baker_glaciers or for the journal article http://onlinelibrary.wiley.com/doi/10.1002/hyp.9453/abstract.

As for competent glaciologists reaching such "hard to imagine conclusions", I would suggest making measurements works pretty well.

It has been fortunate for Washington State to have Marui Pelto working on our North Cascades glaciers over the past 30 years. His latest yearly summary  http://glacierchange.wordpress.com/2013/09/01/north-cascade-glacier-climate-project-2013-field-report/.

Notes on General Sheridan: Missionary Ridge and Yakama War

Gettysburg was in the news this past week as it was the 150th anniversary of the Gettysburg Address. A few days after the famous Lincoln speech a very important Union victory took place in Tennessee that was pivotal in speeding up the end of the Civil War. On November 25, 1863 Union forces took Missionary Ridge (Battle_of_Missionary_Ridge) near Chattanooga, Tennessee. This battle gave control of Tennessee to the Union and provided the key supply route for General Sherman's March across the South in 1864.

A couple of former Washington Territory residences were major players in the Battle of Missionary Ridge, Ulysses S Grant and Philip Sheridan. Sheridan and his men were instrumental in the battle. They were assigned to take some Confederate gun pits on the valley below the ridge as a means to distract the opposing Confederate army from the main assault by General Sherman. However, once the pits were taken the Union forces were subject to fire from the ridge above. A combination of poor communication and wanting to find protection led Sheridan as well as other field commanders to advance up the ridge. The Confederate forces had built their trenches on the ridge crest instead of what is termed the military ridge line. Hence, the curve of the slope provided significant cover for advancing Union forces who then took the ridge and the route was on. 

Grant's time in Washington was rather sad. He was quarter master at Vancouver in the early 1850s and it was during that time he gained a reputation for drinking which continued at his next station. He ultimately resigned from the military only to be reinstated after the start of the Civil War.

Sheridan's first war experience was in Washington Territory. He fought in two engagements with the Yakama (tribal spelling). First near present day Toppenish and later at the Cascades on the Columbia at present day Bonneville Dam.

I've been reading Sheridan's Memoirs with attention to his brief time in Washington State and Oregon. He described his first military action, "On the second day out I struck a small body of Indians with my detachment of dragoons, but was unable to do them any particular injury beyond getting possession of a large quantity of their winter food, which their hurried departure compelled them to abandon. This food consisted principally of dried salmon-pulverized and packed in sacks made of grass-dried huckleberries, and dried camas; the latter a bulbous root about the size of a small onion, which, when roasted and ground, is made into bread by the Indians and has a taste somewhat like cooked chestnuts."

During his trip toward Washington Territory, Sheridan made an early environmental observation in relation to environmental damage and the consequences to the Pit River Indians in northern California. "In prosperity they mainly subsisted on fish, or game killed with the bow and arrow. When these sources failed they lived on grasshoppers, and at this season the grasshopper was their principal food. In former years salmon were very abundant in the streams of the Sacramento Valley, and every fall they took great quantities of these fish and dried them for winter use, but alluvial mining had of late years defiled the water of the different streams and driven the fish out. On this account the usual supply of salmon was very limited."

Red Mountain AVA Vineyard Expansion

Red Mountain AVA (American Viticultural Area) is a hot (both commercially and climatically) vineyard area east of Benton City. The hot summer weather, windiness, south facing aspect and a mix of ice-age flood soils mantled with windblown silts and volcanic ash produce grapes that are much desired and acclaimed by wine makers and drinkers.

The first small vineyard was put in during the 1970s. A few more were added in the 1980s and early 1990s. By 1996 Red Mountain was gaining a reputation for excellent wine grapes. The extent of vineyard plantings in 1996 prior to the AVA designation is shown in this Google Earth image with the future AVA approximately outlined.

The Red Mountain AVA was designated in 2001 as a means to distinguish it from the broader Columbia Valley and Yakima Valley. Since that time there have been a variety of sites that have since carved out distinct AVAs of various sizes and peculiarities of climate and soils.

Since 1996, shown above, and since the designation of the Red Mountain AVA, the extent of vineyards has expanded considerably.

2013

To the west (left in image above) of Red Mountain AVA is the Yakima River which flows from west to east and then makes a sharp turn to the north where it flows along and below the west of the AVA. Benton City is within the bend. Prior to the vineyard plantings, Red Mountain was mostly scrub steppe land that had been heavily grazed and had a fair covering of cheat grass, an invasive poor nutrition grass which takes on a red hue in late May after it dries out.

The water to irrigate the vineyards has been for the most part via wells. But a big expansion of vineyards is coming. The Kennewick Irrigation District (KID) is working on a $20 million dollar project to irrigate 1,700 acres within and adjacent to the AVA (KIDRM_Proposed_Irrigation_System_Map111212.pdf). The water will be from the Yakima River via a pump station under construction at the southwest end of the AVA. Most of the wells will be replaced by the pump system.

 KID obtained the water through a complex formula of reduced water usage as formerly irrigated ground in the District was converted to less water intensive uses, conservation and a bit of legal action that was settled with agreements with Washington State Department of Ecology as well as the Yakima Nation.

The costs of the project were fronted by a State of Washington Program for water in the Columbia Basin, but KID will pay the costs back via fees and payments from water irrigators that use the system. In addition KID currently owns many of the tracts of land that will be served by the water and is holding an auction to sell many of those parcels on Saturday, November 23 via auction. The auction will be a big test to see if this scheme is going to pay both for the KID and for vineyards on Red Mountain. It also a chance for would be wine grape growers to get in on the hot Red Mountain AVA.

Seattle Coal Imports, Cement and Carbon Tax

The production of cement is a major source of CO2 into the atmosphere. Various estimates put concrete production as responsible for a bit more than 5% of all CO2 emissions.  While driving over the high concrete span over the Duwamish River in Seattle I got a glimpse of Seattle's single biggest CO2 source, Ash Grove's Seattle cement plant.

Cement plant from the West Seattle Bridge

Cement is inherently a big releaser of CO2. The chemistry is simple CaCO3 (calcite) + heat --> CaO (lime) + CO2. Hard to get around that CO2 source for what has been a basic building material for a very long time. I should add that there are some significant nuances in that other elements are then added to make say Portland cement such that the final product CO2 emission will vary depending on the specific concrete product.

As noted above, my view of this CO2 source was provided by a fair bit of concrete ifrastucture. In addition to the chemical reaction, turning limestone (calcite) into lime and CO2 requires a lot of heat. And hence, cement production often utilizes coal in the production of heat for the reaction. The tops of a couple of a coal piles can be seen at the cement plant in the image above and in the this areal view of the Ash Cement site.

The primary limestone and coal source for the cement production is form Texada Island located between Vancouver Island and the mainland of British Columbia. The limestone is mined on Texada and coal is mined from an underground high BTU coal deposit on Vancouver Island not far from Texada Island.

All in all a fairly efficient operation. Ash Concrete has a position statement regarding greenhouse gases and regulatory mechanism HERE. While Ash (as of 2009) is not convinced anthropogenic CO2 will have a significant impact on climate change that will harm humans (perhaps nuance versus flat out denial), they take a position that a carbon tax would be preferable to a cap and trade scheme approach. It is an interesting read to get an industrial perspective with more than just a fossil fuel burning component.

Curved Rock Piles on the Olympic Peninsula North Coast

West of Twin Rivers on the Olympic Peninsula's north shore are a series of curved land forms extending out from the shore within the tidal zone.

The road is State Highway 112

Last week I had a chance to explore this coastal reach. I had a nice break in the weather to do it and just enough afternoon light and out going tide to get a reasonable look at this lonely stretch of coast. I should add a few notes here regarding the walk on this shore. It is not frequently visited by humans and is very treacherous walking - essentially long stretches of the equivalent of horizontal talus with a variety of slippery features from sea weed to mud covering the rocks.

The curved land forms consist primarily of boulders on a bedrock cut platform shoreline. The piles of boulders form the curved forms and the curves come in various sizes. The larger and more continuous, the more consistent the curve with smaller more chaotic piles of rocks being common as well including within the more prominent curved rock forms. It is perhaps easier to see the features in aerial views, but they can be fairly easy to discern on the ground (tide flat); however, the wide scale does not lend the features to being easily captured in pictures.

The rock piles form protected pools on the wave cut platform shore

The boulders in the curved lines are different than the bedrock on the platform and at the shoreline bluff. The boulders are harder sandstone and siltstone and occasional glacial erratics while most of the platform and bluff is claystone.

This entire reach of coast is lined with very unstable deep-seated landslides associated with the very weak claystones. The source of the curved piles of rocks is the result of large landslides that have slid out onto and across the wave cut platform transporting harder more resistant rocks to the outer edge of the slide area. After the slides take place, the wave action erodes away the soft broken landslide debris leavng behind a lag of harder boulders around the perimeter of the slide area. At least that is how I am interpreting the features of curved piles of rocks. I have a chance to better test this idea at another site, but it will have to wait for another trip out there.

These rocks are Oligocene marine and non marine rocks and are fossil bearing.

There was something of great interest to the gulls in one of the pools

Back on the road pictured in the initial Google Earth image

The first time I drove this road was during a heavy rain storm at night. Even at night it was obvious this section of highway was on a landslide or a series of deep-seated landslides. It is a very slow section of road and requires frequent patching and monitoring.
