glaciers are found in the Sierra Nevada above 10,000 feet in elevation,

The magnitude and rate of change in surface area are variable among the seven Sierra Nevada glaciers. These differences suggest that factors other than regional climate influenced these changes. For example, structural features such as cliffs can protect against loss by shading solar radiation, and avalanching from cliffs can enhance snow accumulation on a glacier.
The observations in the Sierra Nevada are consistent with the loss of glacier mass reported worldwide.
