Clallam Formation and Vertipecten fucanus (Dall, 1900)

I had a bit of a hike on a closed logging road to access a steep slope. The road cut into the slope has a few small scale slumps exposing the underlying sandstone of the Clallam Formation.


The Clallam Formation is on north coast of the Olympic Peninsula along the shore of the Strait of Juan de Fuca from Slip Point on the east end of Clallam Bay to Pillar Point. The sandstone dominated formation forms a slight outward bulge of the coast line with steep bedrock cliffs down to a bedrock platform shoreline. I did not have the opportunity to get out along the shore. The cliffs and tidal platform were an early attraction for geologists and in particular paleontologists because the abundant well preserved fossils in the formation. William Healey Dall (https://en.wikipedia.org/wiki/William_Healey_Dall) spent time on this coast and described many of the mollusk fossils.

While I was not able to visit the shore, I did get to examine the rock on the road cuts and slumps I passed, and I readily found fossils.



Finding the well preserved fossil, I turned to Addicott, 1976 to see if I could identify the find. Addicott notes that Vertipecten fucanus (Dall, 1900) is the most characteristic mollusk in assemblages from the Clallam Formation. Given that I observed this fossil in most of the outcrops I looked at, I can back that up.

For non paleontologists, you could simply call these big scallops. Once upon a time I taught a paleontology lab class. I was always just a day ahead of the students and since then much of what I learned leaked out of my head. However, I have always had an appreciation for the detailed work of paleontologists and Addicott's detailed report help me understand the formation I was exploring.

Voting in the Time of COVID-19

 The State of Wisconsin is trying to run an election at the same time as a pandemic that requires social distancing to stop the spread of the virus. The difficulty of running an election with social distancing is beyond possible. The election offices have had a huge number of absentee ballot requests as voters try to social distance and poll workers decline to expose themselves to virus pathways.

The State of Wisconsin's attempt to modify the election process by having greater flexibility with  absentee ballots be sent out, received and returned during a pandemic was over ruled by a 5-4 Supreme Court descion https://www.supremecourt.gov/opinions/19pdf/19a1016_o759.pdf.

The majority opinion reference COVID-19 one time near the end

"The Court’s decision on the narrow question before the Court should not be viewed as expressing an opinion on the broader question of whether to hold the election, or whether other reforms or modifications in election procedures in light of COVID–19 are appropriate".

While the majority argues this is case was a narrow question, I suspect all " other reforms or modifications" would also be ruled on in a narrow manner. Further, while the majority mentions COVID-19 once, the ruling was otherwise oblivious to the consequence of the pandemic and alterations that must be done to stop the spread of the virus.

During the time of COVID-19 Washington State can be grateful that we have vote by mail (You can also simply drop your ballot off at ballot drop off stations). It is a much safer approach. 

In a different era (the early 2000s), I was on a county council that looked at our various voting options under new federal law passed after the 2000 presidential election. The new law eliminated punch card voting. Our County Auditor brought forward a preferred option - vote by mail.

The alternatives were far more expensive - costs of new voting machines, cost of software associated with new machines, cost of storing the machines and the costs of simply running polling stations all over a sprawling county with a city, small cities and low density farming and forest communities including parts of the county that required leaving the county to get to (Newhalem) or leaving the country (Point Roberts). The cost disparity was so great that the choice of vote-by-mail was by far the superior approach.

As I recall we were the second county to follow this route and now the entire state votes this way. Yes, we have to wait a bit to know election results. Election night, early returned ballots that have been processed (signatures verified) are counted. All ballots post marked election day or earlier are counted. In close elections it may be about a week before the final result is known, but it is now simply part of how elections go in Washington State. No more staying up late while exhausted election workers process ballots being delivered from the far reaches of the county.

Alas changing to vote-by-mail is politically fraught elsewhere in the Country with the debate having more to do with political power than voting efficiency and fairness. The very fact that the voting issue in Wisconsin ended up in the Supreme Court suggests as much as well.

Following Quercus garryana

I am making another attempt to be a tree follower (squirrelbasket/tree-following). My effort last year HERE was a fail. The problem was the tree was on a long vacant property that shortly shortly became not vacant. The tree remains, but I was unable/unwilling to trespass to get a good look to identify the tree. 

I have plenty of trees on our own property and I am only just beginning to get my head around the nuances of the forest. For this year I will follow a new tree.  

Quercus garryana 
Garry oak or Oregon oak or Oregon white oak 

I planted this tree last spring. The fence is to keep the deer from nibbling the tree. The soil is very hard glacial till. In western Washington oaks grow in the excessively well drained prairie sites, but there are patches in drier areas of the San Juan Islands as well as the Columbia River Gorge and valleys on the east slopes of the Cascade Range.

Samish Island is within the rain shadow of the Olympic Range and hence a bit on the dry side. There are oaks on the south facing bluffs of the island and I noted a small stand across Samish Bay on the lower slopes of Chuckanut Mountain. The biggest challenge to the oaks is shading out by taller evergreen trees - particularly the Douglas firs.

Not much to report at this late winter early spring time. Waiting for the leaves to come out and seeing if the tree tolerated saturated ground conditions from the very wet winter.

Covid Nonpharmaceutical Intervention -Lessons from 100 Years ago

Vox News (coronavirus-social-distancing-economy-deaths) notes the consequence ending school closures and banning public events too soon. The article is a take on a 2007 JAMA paper that analyzed data from the 1918-1919 influenza pandemic (Nonpharmaceutical interventions implemented by US cities during the 1918-1919 influenza). Informative regarding methods to tamp down pandemics that were used 100 years ago and still apply today. And a cautionary story of ending interventions too soon. And perhaps suggests that the CDC guidance as well as state health decisions should lean towards closures to 3 or 4 months or more depending on how this pandemic proceeds.

You can be a COVID hero -- from your own home

I have a loved one in Illinois and found this message on sheltering in place worth sharing.



I am fortunate that in my work avoiding social contact is an easy task. It is very rare that I meet clients or attend meetings. What meetings may take place are easy to avoid. For others this virus is a much harder dilemma.

Maybe this chart and vox article will add some perspective. I know that when I saw this chart a few weeks ago I started to isolate as much as I could.



Be healthy and be a hero.

Late Winter View of Two Volcanoes

Much of Washington State enjoys views of volcanoes. In northwest Washington, Mount Baker is the scenic mountain. I can see its summit from my office window although much of it is obscured by intervening lower mountains. The view of Baker is typically better a bit further back from the mountains. Crossing the Samish Flats in Skagit County, I had a nice view of the mountain through a gap in the Northwest Cascades.

Jagged peaks in the center are the Twin Sisters 

Seeing Baker on a clear late winter day is great. While taking in the view of Baker, it crossed my mind that the other volcano I had observed earlier in the day was about the same distance away as the view I had of Baker. So I took a picture of Baker with the same focal setting I had used earlier in the day when taking a picture of Mount Rainier. When I got home I checked the distances and both picture locations were about 31 miles from the subject mountain.

Mount Rainier 

The view of Rainier from Pierce County southeast of Tacoma is a bit of jolt. 4,000 more feet of elevation and the corresponding mass is an awesome site to take in.
