Aerial view of Sperry Glacier in Glacier National Park, Montana. Sperry Glacier occupies a broad, shallow cirque situated just beneath and west of the Continental Divide in the Lewis Mountain Range of Glacier National Park, Montana. Due to its position on the Continental Divide the glacier is influenced by both maritime and continental air masses.
