Warm Springs Reservoir
Public
Harney County
The high desert around Warm Springs Reservoir, on the Malheur River southeast of Burns, exposes weathered volcanic ground that yields agate, jasper, and petrified wood across public BLM land. Collectors find white, gray, and mossy agates alongside red and yellow jasper on the surface, with quality improving on the more remote ground away from the main roads. The reservoir lies in the broader Harney Basin rockhounding country that has drawn collectors to eastern Oregon for decades.
