Also come to Connecticut. The CT river valley is composed of two continents, or fragments of two.

Man I love this topic. I've often thought a great archeologic investigation would be to dig around at the estimated Tsunami high water above known inhabited locations in Puget Sound. My theory is that possessions, or parts of canoes or long houses and the like should be found up there, now far from the shoreline.

Interesting article , David. The subsidence seems counterintuitive to me. One could imagine a subduction earthquake and subsequent plate movement actually pushing things up, like a berm. But obviously there are areas of local settling. Another thing; we have a good example of the boundary formerly-known-as k/t ( now k/pg ) right here in Utah . Above the towns of Ferron and Orangeville (I believe) an amateur geologist found evidence of the “Dino Killer” smoking gun, namely anomalously high iridium content. It’s in the North Horn formation.

Mr. Knouff, I agree but if you look at the drawing, the subsidence is due to post quake relaxation and settling, sort of like what happens after one exercises and one slumps to the ground! Have you been to to that K/T spot? I hope so. David

You can see upright buried root systems and stumps from large trees from this event at the mouth of Scott’s creek south of 3rd Beach on the Washington coast. Subtle but obvious once you notice it.
