Four overlapping dacite domes form the Black Buttes lava dome on the lower western flank of Mount Shasta. This view looks NW from the summit of Black Buttes, at the tops of two of the domes with the outskirts of the town of Weed below. Pyroclastic flows accompanying formation of Black Buttes extend 10 km S and 5 km N, and underlie currently populated areas.
