A group of four small late-Pleistocene to Holocene volcanoes referred to as Stepovak Bay 1 through 4 lies along the NE-trending snow-covered ridge extending from the top center to the lower left. The chain of volcanoes lies NW of Stepovak Bay (lower right); individual centers are not distinguishable because of the extensive snow cover in this NASA Landsat image (with north to the top). The larger Kupreanof stratovolcano lies out of view at the upper right.
