The area receives an average annual snowfall of approximately 400 inches, with an average peak snowpack depth of around 120 inches. The nearby Grand Targhee and Jackson Hole ski resorts benefit from this consistent snowpack, providing prime skiing conditions throughout the winter season.
Climate trends in Thumb Divide show an increase in temperature over the past decade, resulting in a decrease in snowpack duration and overall volume. This can have significant impacts on downstream hydrology constituents, such as the Teton River and Teton Reservoir. The snowpack acts as a natural reservoir, storing water throughout the winter and releasing it gradually in the spring and summer, but with the current climate trend, water availability for recreation and agriculture may become increasingly limited.
Therefore, monitoring and understanding the snowpack in Thumb Divide is crucial for the management of downstream water resources, as well as for the numerous winter recreation activities that rely on a healthy and consistent snowpack.
