Second Afternoon Session Added

COGS Geo-Exploration: Barnes Butte, Prineville, OR

Led by Carrie Gordon

March 31, 1:30 - 4 PM

Please join Carrie Gordon, retired Ochoco National Forest geologist, and Derek Loeb as we walk the Barnes Butte park trails. Trip starts at the Barnes Butte Trailhead in Prineville, just north of Barnes Butte Elementary School. After a short organizational discussion and introductory geologic framework, participants will walk the park trails, roughly 2 ½ miles round trip with only minor elevation changes (we will not be climbing to the summit which is a goat scramble). Our view will be looking across the Crooked River Caldera to the high Cascades with a short side-trip to look at the gated adits of the Barnes Butte mercury mine. Along the way, we will explore outcrops of Rhyolite and deposits of Mazama Ash and other geologic curiosities.

A location to meet for ride sharing or caravaning from Bend will be arranged.  Please contact Derek Loeb at with questions?
