Geologists examining evidence of large offset along the Hosgri fault

Detailed Description

Geologists comparing existing geologic maps with the outcrop behind them and evaluating the evidence for how these rocks near Point Piedras Blancas along the California coast arrived at their present state-essentially sedimentary rocks that were deposited horizontally now dipping at a near-vertical attitude. Researchers have suggested that these rocks were once adjacent to simiar rocks exposed near Point Sal ~55 miles to the south and translated into their current position by the San Gregorio-Hosgri fault zone.
