Rock Glaciers Key to Utah's Water Supply, Study Finds
US · Published Sep 22, 2026
A new study by Brigham Young University (BYU) and the Utah Geological Survey highlights the critical role of rock glaciers in Utah's water supply.
These slow-moving masses of ice and debris, such as the one on Mount Timpanogos, release water long after snowmelt, providing a vital resource for a state that relies on snowpack for 95% of its water.

Impact & Risks

The findings are particularly significant for Utah, where over 90% of the state is currently experiencing severe drought conditions, according to the U.S. Drought Monitor. Rock glaciers provide a critical water source during dry periods, especially in late summer when other supplies are limited. The study's results could influence water management strategies in the Mountain West and other arid regions. However, the reliance on these glaciers also highlights the need for sustainable water management practices to ensure long-term availability.
