Lone Pine Fans and Earthquakes



At Lone Pine, California, a distinct alluvial fan near town is offset by the Lone Pine Fault. Closer to the range front, extensive bajada-forming fan surfaces are littered with granitic boulders. We sampled boulders from fan units with different relative weathering intensities and used the resulting cosmogenic data to both estimate fan ages and earthquake recurrence intervals.
