Mud Creek Glacier, the southernmost glacier on Mount Shasta, lies on the mountain’s southeast side at about 10,915 feet and is one of at least seven glaciers recognized there by the United States Geological Survey. Considered relatively young at about 1,000 years old, it was not formally recognized on a topographic map until 1987. The glacier has carved Mud Creek Canyon, leaving hanging-valley features, moraines, and Mud Creek Falls below. It is also linked to some of Mount Shasta’s most serious hazards, as loose scree and rapid melting can trigger mudflows and landslides, including a major 2014 mudflow that sent debris downstream and damaged roads and bridges.
