Glaciations of the Sierra Nevada, California, USA
The Sierra Nevada is a c. 4000 m range of mountains paralle1 to the North American Pacific Coast that was repeatedly glaciated during the climatic fluchrations of the Quatemary. The glacial record on the eastem side of the range includes eight named Pleistocene glaciations and stadials: McGee, Sherwin, Casa Diablo, Mono Basin, Tahoe, Tenaya, Tioga and Recess Peak, as well as the Neoglacial Matt...
متن کاملDistribution of California Black Rails in the Sierra Nevada foothills
California Black Rails (Laterallus jamaicensis coturniculus) have a disjunct and poorly understood distribution. After a new population was discovered in Yuba County in 1994, we conducted call playback surveys from 1994 to 2006 in the Sierra foothills and Sacramento Valley region to determine the distribution and residency of Black Rails, estimate densities, and obtain estimates of site occupan...
متن کاملEmbedded‐sensor network design for snow cover measurements around snow pillow and snow course sites in the Sierra Nevada of California
[1] The design of sensor networks for measuring the mean and spatial distribution of snow depth at the scale of 1–16 km was evaluated by deploying an embedded‐sensor network consisting of ultrasonic snow depth sensors to capture the variable physiographic features around an operational snow course in Yosemite National Park in the Sierra Nevada of California. Manual snow surveys were also carrie...
متن کاملFoundering lithosphere imaged beneath the southern Sierra Nevada, California, USA.
Seismic tomography reveals garnet-rich crust and mantle lithosphere descending into the upper mantle beneath the southeastern Sierra Nevada. The descending lithosphere consists of two layers: an iron-rich eclogite above a magnesium-rich garnet peridotite. These results place descending eclogite above and east of high P wave speed material previously imaged beneath the southern Great Valley, sug...
متن کاملGPS Imaging of vertical land motion in California and Nevada: Implications for Sierra Nevada uplift
We introduce Global Positioning System (GPS) Imaging, a new technique for robust estimation of the vertical velocity field of the Earth's surface, and apply it to the Sierra Nevada Mountain range in the western United States. Starting with vertical position time series from Global Positioning System (GPS) stations, we first estimate vertical velocities using the MIDAS robust trend estimator, wh...
