Huh? This river seems to appear from nowhere before joining another, which, in turn, seems to have appeared from nowhere. Or did it? Learn why springs like this occur, what’s happening below the surface and how Central Oregon's volcanic past of fire and lava helped create one of the most remarkable groundwater systems in the western United States.
Join Black Butte Conservancy for "The Cascades Connection: Volcanoes, Groundwater & the Origin of Springs" next Wed., Nov 4 from 5-6 pm at Black Butte Ranch's Community Center. Dr. Daniele McKay, Senior Instructor in the Department of Earth Sciences at the University of Oregon, will lead the talk.
This is the last evening science talk for 2026 and it is open and free to Sisters friends, Black Butte residents and anyone who is interested. Simply show up! Learn more about the Black Butte Conservancy at blackbutteconservancy.org.
