Overview
The Ivao group of cones along the Krishtofovich Ridge of SW Urup Island contains several well-preserved cones of Holocene age. The first of a group of three young cones, at the NW end of the chain, is the Ivao cone. The SE-most cone bisects a glacial valley, forming Lake Ivao.
The elongated central cone, Krutaya Mountain, is the youngest, and produced a viscous lava flow that traveled to the east.

About the Photo
The Ivao Group within the Krishtofovich Ridge has undergone extensive erosion and the remains are mostly lava flows; it is in SW Urup island and contains three remaining cones. The group is in the center of this September 2019 Planet Labs satellite image monthly mosaic (N is at the top; this image is approximately 40 km across).
