Research shows declining levels of acidity in Sierra Nevada lakes
Sierra Nevada lakes declining levels
2014/9/12
RIVERSIDE, Calif. — California’s water supply depends on a clean snow pack and healthy mountain lakes. The lakes receive a large amount of runoff in the spring from the melting snowpack. If the snow...

Like a detective story with twists and turns in the plot, scientists at the University of Nevada, Reno are unfolding a story about the rapid uplift of the famous 400-mile long Sierra Nevada mountain r...
Influence of lithology on hillslope morphology and response to tectonic forcing in the northern Sierra Nevada of California
Influence of lithology hillslope morphology response to tectonic forcing the northern Sierra Nevada of California
2014/5/20
Many geomorphic studies assume that bedrock geology is not a first-order control on landscape form in order to isolate drivers of geomorphic change (e.g., climate or tectonics). Yet underlying geology...
Measured black carbon deposition on the Sierra Nevada snow pack and implication for snow pack retreat
black carbon deposition the Sierra Nevada snow pack snow pack retreat
2010/8/16
Modeling studies show that the darkening of snow and ice by black carbon deposition is a major factor for the rapid disappearance of arctic sea ice, mountain glaciers and snow packs. This study provid...
