 It is the fifth largest glacier on Mount Shasta, although less than one-third the size of any of the four larger ones (Whitney, Bolam, Hotlum, and Wintun).The Konwakiton is the most frequently visited of Shasta's glaciers, since the standard climbing route up Avalanche Gulch skirts along its western edge above Thumb Rock saddle, with the boot track often only a few feet (about a meter) from the bergschrund at the glacier's head.In 2002, scientists made the first detailed survey of Mount Shasta's glaciers in 50 years.
