Blue Lake Crater, 0.3 x 0.8 km wide, was formed about 1300 years ago by volcanic explosions through pre-existing volcanic bedrock. A least three overlapping craters were formed, with ejecta forming a crater rim only 50 meters above the pre-eruption surface.

Blue Lake Crater in the foreground is one of three overlapping explosion craters located east of Santiam Pass. The craters formed about 1300 years ago by explosions through older volcanic bedrock, and a chain of spatter cones about 6 km SSW of Blue Lake may have been active during the same eruption. Despite its proximity to a major cross-Cascades highway, Blue Lake Crater is one of the least-known Holocene volcanoes of the Cascades. The snow-capped pinnacle of Pleistocene Mount Washington is visible in the background.
