On Wednesday, August 6, I climbed Castle Rock, a steep volcanic plug north of the community of Juntura in Eastern Oregon. I have often noted Castle Rock rising above as I drove east over Drinkwater Pass between Burns and Juntura. Castle Rock is also prominent to the south from many peaks in the southern Blue Mountains. It has 1524 feet of topographic prominence and a distinctive shape.
