This is the largest glacial valley on the volcano, although it does not now have a glacier in it. There are seven named glaciers on Mount Shasta, with the four largest ( Whitney , Bolam , Hotlum , and Wintun ) radiating down from high on the main summit cone to below 10,000 ft (3,000 m) primarily on the north and east sides.
