Quaternary 0 - 2.588 Ma ID: 2988945 | Basaltic andesite and basalt Age: Pleistocene (0 - 2.588 Ma) Description: Flows and flow breccia dominantly of basaltic andesite containing plagioclase, olivine, and pyroxene phenocrysts and olivine-bearing basalt representing part of the volcanic sequence of the High Cascade Range (Thayer, 1937). Unit mostly forms small shield volcanoes, gentle-sided lava cones, and, in places, intracanyon flows Comments: smaller cones and flows Lithology: Major:{basaltic andesite,basalt} Reference: Horton, J.D., C.A.
