Geology Overview: The Saddle Mountains provide the backdrop for this year’s trip – spectacular scenery and challenging geology await us. The Saddle Mountains are located at a geomorphic triple junction, where sediments of the Channeled Scablands, Yakima Fold Belt, and Palouse Hills interfinger. Visually-stunning calcrete paleosols span all three domains. The Stage III-V calcretes, hundreds of thousands of years old, formed in an alluvial lowland setting and on gently-sloping alluvial fans. They serve as a conspicuous marker unit that helps constrain the age of pre-Wisconsin

scabland flooding, local tectonism, and dramatic topographic changes that occurred in the area over the past ~7 million years – from a broad, low-relief floodplain to the high-relief escarpment we see today. A central question remains: where were the ancestral Snake and Columbia Rivers in Plio-Pleistocene time?
The trip will focus on the new outcrops and new insights on the interplay of tectonics, climate, and topography informed by field work completed in recent years. Little of what we will see and discuss is found in any guidebook. Join us for the adventure!
