The northern (bottom) and southern (top) cones at the summit of Krasheninnikov were constructed within a 9-km-wide late-Pleistocene caldera. The southern cone began forming about 11,000 years ago and the northern cone about 6,500 years ago; both have 800-m-wide craters. An eruption about 400 years ago produced the small Pauk cone within the northern crater (lower right).
