Wheeler Peak Cirque

Great Basin NP

Wheeler Peak, standing at over 13,000 feet, provides classic examples of the erosional forces of glaciation. Ice pried, plucked and carried away quartzite from the cool northeast slopes of the higher reaches in the Snake Range. When the glaciers melted and receded, deep bowls called "cirques" were exposed. Also visible today are the rocky hummocks called moraines. Wheeler Peak Cirque shelters the only known remaining glacier in Great Basin NP. Photo © copyright by Robert Faucher.
