This geological map and associated information on rock units at or nearby to the coordinates given for this locality is based on relatively small scale geological maps provided by various national Geological Surveys. This does not necessarily represent the complete geology at this locality but it gives a background for the region in which it is found.

| Pliocene - Miocene 2.588 - 23.03 Ma | Early Winema Volcanic Field Age: Neogene (2.588 - 23.03 Ma) Description: Rocks of strato-volcanoes and domes, flows rhyodacitic; lava flows; rhyodacite; rhyodacite Lithology: Major:: {rhyodacite flows} Reference: R.L. Smith, W.P. Roe (compilers). Oregon Geologic Data Compilation, release 6. State of Oregon Department of Geology and Mineral Industries. [20] |
| Pliocene - Eocene 2.588 - 56 Ma | Silicic vent rocks Age: Cenozoic (2.588 - 56 Ma) Stratigraphic Name: Westfall Butte Volcanics Description: Plugs and domal complexes of rhyolitic, rhyodacitic, and dacitic composition; includes related near-vent flows, flow breccia, and deposits of obsidian, perlite, and pumice. Locally includes resurgent domes related to caldera complexes. In southeast Oregon many domal complexes younger than 11 Ma exhibit a well-defined southeast to northwest age progression (Walker, 1974; MacLeod and others, 1976) from about 11 Ma to less than 1 Ma Comments: The rhyolitic domal complexes become younger toward the northwest. Includes volcanics of Westfall Butte (OR148), which contains basalt, and rhyolite of Star Mountain (OR149). Lithology: Major:{rhyolite,dacite} Reference: Horton, J.D., C.A. San Juan, and D.B.
