Cerro Colorado tuff cone is one of the most prominent features of the Pinacate volcanic field in Mexico. This aerial oblique view from the NW shows the 1-km-wide crater with the highest point on the S rim. Tuff beds that compose the S rim dip inward up to 20-25 degrees. Cerro Colorado's crater was formed during several episodes of phreatomagmatic eruptions from multiple vents, during which portions of the tuff cone slumped into the crater.
