Geologists have documented 70 frozen deposits hidden beneath debris on Mount Timpanogos in Utah. The survey confirms the presence of 396 million gallons of ice, which is essential to understanding the state's future water supply.
Why it matters
Understanding these hidden reservoirs is critical as meltwater provides over 95% of Utah's total freshwater supply. Locating and cataloging these reserves informs how the state manages water resources in a changing climate.
The Timpanogos rock glacier consists of 83% ice and 17% rock, with an average ice thickness of 61.7 feet. Researchers established these figures by performing 232 gravity measurements to calculate density variations.
The details
Researchers utilized a gravimeter—an instrument designed to measure minute differences in the Earth's gravitational pull—to identify the high-density ice buried beneath surface debris. This approach was supplemented by snow probe data, satellite light reflectance imagery, and local climate reports. The resulting data characterizes the structure as a mass of ancient permafrost originating approximately 20,000 years ago.
Timeline
20,000 years ago: The period when the ancient permafrost within the rock glacier originated.
May 2024: The period when researchers began planting snow probes on the mountain.
September 2026: The month the geological survey documentation was completed.
The Tech Race
This study advances the effort to quantify alpine water reserves which currently rely on incomplete surface-level observations. It follows a growing trend of using gravimetric sensing to map subsurface cryosphere structures across high-altitude regions.
While this survey is currently a research-stage documentation of natural resources, the data will inform state water policy regarding long-term freshwater availability. Residents of Utah should anticipate these findings to influence future infrastructure and conservation planning.
The takeaway
This study establishes a new volumetric baseline for mountain water reserves in Utah. Watch for future findings as researchers extend this gravimetric mapping method to other rock glaciers in the region.
What happens next
Researchers plan to conduct follow-up studies to identify which other rock glaciers in the state are currently accumulating ice.
