A groundbreaking study has unveiled a substantial rock glacier concealed beneath Mount Timpanogos in Utah. This glacier contains approximately 1.5 million cubic meters of ice, equating to the volume of 600 Olympic swimming pools. Conducted by a team of researchers, this discovery sheds light on previously uncharted water reserves.
Detected using advanced gravity measurement techniques, the glacier's composition reveals that about 83% of it is pure ice. These findings suggest that a broader reservoir of hidden ice may be present across various mountain ranges worldwide, potentially reshaping our understanding of glacial formations.
Key Findings
- The Timpanogos Rock Glacier comprises about 1.5 million cubic meters of ice, equivalent to 600 Olympic swimming pools.
- Researchers utilized a gravimeter to measure gravitational variations, allowing them to construct a 3D model of the glacier's hidden ice, which includes around 120 feet of ice buried beneath the surface.
- This study was published on August 26, 2026, in the Journal of Geophysical Research, suggesting that rock glaciers are a relatively new phenomenon formed after the primary Ice Age glaciers melted.
- Globally, approximately 50,000 recognized rock glaciers might collectively hold about 48 gigatons of water, comparable to the volume needed to fill 400,000 Olympic swimming pools.
- The unique geological conditions of the Wasatch Mountains facilitate the formation of rock glaciers, where debris falls protects underlying snow from rapid melting, resulting in significant ice reservoirs.
The study's findings are critical not only for understanding regional hydrology but also for assessing the impacts of climate change on water resources over time. As glaciers retreat globally, these hidden reserves may play a vital role in future water supply frameworks, demonstrating the importance of ongoing research into glacial landscapes.
