Prehistoric Rock Art of Nevada and Eastern California

Recording Prehistoric Rock-art: A Three Dimensional Approach

The Northumberland and Durham Rock Art Project (NADRAP), a three year English Heritage funded project formally completed in July 2008, set out to pilot a meth­ odology for creating an index of around 1,500 known rock art panels located across two counties of the north-east of England. Principally using around 60 volunteers recruited from the local community, this would provide a georeferenced d...

Laser ablation-inductively coupled plasma mass spectrometry for the characterization of pigments in prehistoric rock art.

In this work, several red-colored paintings of post-Paleolithic schematic style found in 10 different shelters in the vicinity of the Vero River (Huesca) were sampled and subjected to analysis by means of scanning electron microscopy-energy-dispersive X-ray spectrometry (SEM-EDX), Raman spectroscopy, and laser ablation-inductively coupled plasma mass spectrometry (LA-ICPMS). The goal of this re...

Geophysical Studies of Basin Structures along the Eastern Front of the Sierra Nevada, California

A seismic and gravity survey along the eastern front of the Sierra Nevada, California, between southern Owens Valley and the Garlock fault, outlines a series of basins with maximum depths ranging from 5,000 to 9,000 ft. These basins follow the front of the Sierra Nevada in a continuous chain with one interruption of about 10 miles near Little Lake. The gravity anomalies indicate that the basins...

Glacial erosion and relief production in the Eastern Sierra Nevada, California

The proposal that climate change can drive the uplift of mountain summits hinges on the requirement that glacial erosion significantly enhances the relief of a previously fluvially sculpted mountain range. We have tested this hypothesis through a systematic investigation of neighbouring glaciated and nonglaciated drainage basins on the eastern side of the Sierra Nevada, CA. We present a simple,...
