A view from a plane of Pavlof Sister (left) and the larger Pavlof Volcano (right) observed above the clouds over the Alaskan Peninsula. The view is to the south from the plane. The northeastern portion of the summit of Pavlof Volcano (right) possibly displays some minor ash deposits from minor Strombolian bursts, but it could also be a snow-free portion of the summit.
