Ellensburg Formation field trip over at Dan McShane’s blog.

Occasionally, Dan McShane’s Reading the Washington Landscape blog (link at right) and this one overlap in subjects. Dan has just posted a nice description of Ellensburg Formation ash, lahars and other sediments in roadcuts near Ellensburg. These sedimentary units were deposited in the intervals between the great Columbia River basalt lava flows.

His post is here, with wonderful photos of the really interesting outcrops. Oh, that clear blue sky! It looks warm over there!
