Blue Lake Crater in the foreground is one of three overlapping craters located east of Santiam Pass. The craters formed about 1,300 years ago during explosions through older volcanic bedrock; a chain of spatter cones about 6 km SSW of Blue Lake may have been active during the same eruption. The snow-covered summit of Pleistocene Mount Washington is visible in the background. Photo by Lee Siebert, 1999 (Smithsonian Institution).
