Based on the home page on October 28, 2023, I started at the Salt Creek Recreation Area.

The page is missing a link to the corresponding Wikipedia article. To fix, I added the hashtag property salt-creek-recreation-area to the page front matter (this will not be required in the future).

With no direct link, I manually navigated to the page at /en.wikipedia.org/wiki/Salt_Creek_Recreation_Area.

I have some history with Port Angeles.
Port Angeles borders the Strait of Juan de Fuca, which is a reflection of the geological history of the region. In hindsight perhaps the Olympic mountains would have gotten closer to Jasper, but decision made:
The Wikipedia article doesn’t say much about the geology of the region. Try the Salish Sea.
The Vashon content doesn’t have much geology, so I backed up to the Georgia Depression, which mentions soils of Georgia Depression (Wikipedia)
Start posting these streaks one at a time.
