Dotsero Crater

Dotsero Crater is an elongate, long by wide, maar incised into sedimentary strata of the side of a mountain, called Blowout Hill, and local, irregular, mountainous topography. At an elevation of , its north rim lies about higher than its south rim. Dotsero Crater is about deep. It is part of a maar and scoria cone complex in which the associated scoria cones are constructed along a NNE-SSW line on either side of the maar and is perched near the upper edge of steep sided canyons about above the valley floor of the Eagle River. The axis of the maar and scoria cone complex aligns with the axis of a local syncline. Associated with the maar and scoria cones is a lahar and -long lava flow. Dotsero Crater lies northeast of Dotsero, Colorado near the junction of the Colorado River and the Eagle River.
