Call for Chuckanut fossil photos

Readers are requested to send in photos of Chuckanut fossils for an eventual website page dedicated to them. Photos should be at least 800 x 600 pixels; identification may be attempted if you don’t know what it is, but a rogues file would be fun to look at and possibly useful for researchers. There was a major effort to identify and catalogue fossils in the WWU collection last summer, but there are probably still unknowns out there in the outcrops. Email photos with the best location info you can obtain, preferably GPS. Otherwise send along a screen shot from  Google Earth or elsewhere, with the location marked. Send to:     tuckerd@geol.wwu.edu

I’ll stick in a few photos to inspire you. The first one was sent by M. Brewer just this morning.  Thanks! DT

Racehorse Creek landslide. Click to enlarge this and all images.

The Sabalites genus lives today. This one was photographed in Florida.

Glyptostrobus dakotaensis (Heer) Brown; the only extant species lives in SE Asia in swamps.

This heavy chunk o' petrified log was packed out of Silver Creek after the Jan. 2009 flood.

General references for the Chuckanut Formation:

A succinct introduction to the Chuckanut is “Geology and paleontology of the early Tertiary Chuckanut Formation” by G. Mustoe, R. Dilhoff, and T. Dillhoff, 2007. This appears in the 2007 Cordilleran GSA Field GuideFloods, Faults, and Fire: Geological Field Trips in Washington State and Southwest British Columbia.

This Northwest Geology Field Trips website has a description of the Chuckanut Formation here.
