I thought I’d see you here.
Someone, I thought on this thread but maybe another, posted a link to a New Yorker article featuring a geologist from OSU.

Somehow what I recall Mr. Alvey teaching us about wasn’t even discovered until the past decade?

Between those and the upthrust bluff at the south end of Sunset Beach, I’ve always figured Coos Bay was on borrowed time. And all of our emergency services are built on fill and there probably won’t be 100 yards of useable road in the county, anyway. No electricity, no treated water.... I can imagine a scenario in which cars are siphoned for chainsaw fuel, and wood heat is all we’ll have.
I fish the dune lakes, so I’ve studied them in topographic maps. It’s not difficult to envision the lakes inshore from the dunes...Eel Lake, Tenmile Lakes... being stream systems that were blocked off when the dunes were upthrust.
