Abstract

The central Oregon Cascades have been shaped by the interplay between tectonics, volcanism, and geomorphic forces including glaciations, and hydrology. As a result of the rich interplay between these forces, mafic volcanism here can have surprising consequences, including considerable tephra footprints, lava flows, water shortages, transportation and agricultural disruption, and forest fires. This multidisciplinary field trip will focus on mafic volcanism, but will also prominently feature the hydrology, geomorphology, and ecology of the area and how it influences and is influenced by mafic volcanism. We will visit mafic volcanism at the Sand Mountain volcanic field and Santiam Pass area, McKenzie Pass, and the southern Bend region. This field trip will also feature a total solar eclipse, the first visible in the USA in over 25 years.
