Ruspen glacier

Ruspen is a newly discovered glacier by OGI on the north side of South Sister below its summit. This glacier has existed for many centuries yet was never added to U.S.G.S. maps. It is above the three Skinner glaciers and has extensive debris cover on its terminus. It is still an active glacier and due to its setting may be the most robust glacier to climate warming on South Sister.
