Prediction of water retentive capacity of high elevation snowpacks on the east side of the Sierra Nevada

Abstract

Two major deformational events affected the metamorphic rocks of the Rush Creek drainage. Dl deformation formed a series of northeast trending folds during the mid-Paleozoic Antler orogeny. D2 deformation formed northwest trending main phase F2 folds and S2 cleavages and late phase small scale folds and crenulations during the Late-Jurassic Nevadan orogeny. The Gem Lake shear zone is a sequence of highly deformed and mylonitic rocks making a ductile shear zone between the Rush Creek sequence and the overlying Koip sequence. Planer zones of high strain are possibly Dl and D2 deformation thrust faults.
