Jason in the Middle Columbia Basin looking northeast across the Columbia River to the Bingen anticline, which is underlain by a thick section of Columbia River Basalt.

The Middle Columbia Basin of north-central Oregon lies across the axis of the High Cascades volcanic arc, stretching from Cascade Locks east to Biggs and southward from the Columbia River to Tygh Valley. Ongoing Geologic mapping in the basin by the Oregon Department of Geology and Mineral Industries is providing new insight into the middle Miocene to present volcanic and structural development of the region. This talk will summarize local Columbia River Basalt Group stratigraphy, discuss new geochemical data and geochronologic constraints on late Miocene to Pleistocene Early to Late High Cascades Volcanic Rocks, and characterize the major structural trends in the region.
