Black Butte is a prominent small stratovolcano east of the Cascade Range crest. Despite its youthful profile, Black Butte is older than many other Cascade Range stratovolcanoes because of its position in a rain shadow to the east. Potassium-Argon dates average around 0.45 million years ago (Taylor, 1981). A NW-SE-trending chain of Pleistocene cinder cones lie east of Black Butte, and other Pleistocene cinder cones lie to the south.
