Nine small Mesozoic plutons in TJmatilla County, northeast Oregon, crop out within an area of 58 sq km in the Blue Mountains. The plutons are divided into an earlier series of probable Permian-Triassic age and a later intrusive series of probable Late Jurassic to Middle Cretaceous age. The earlier rocks...

Stratigraphic measurement of the 1,238-rn thick Cowlitz Formation in the
southwest Washington type section along Olequa and Stillwater creeks reveals complex
facies succession of wave- to tide-dominated deltaic sequences. The underlying, 625-rn
thick upper member of the McIntosh Formation (as mapped by Wells, 1981) is composed
of two units: a...
