Debris flow deposits in Chalone Creek, Pinnnacles National Monument, San Benito County, California

This view shows the dry stream bed of Chalone Creek in eastern side of Pinnacles National Monument (San Benito County). The image shows a plant community partially established on stream bed after a massive debris flow the previous year. In 1998 heavy rains resulted in debris flows that destroyed the bridge and spread gravels throughout the valley. The debris flows possibly contributed to the death of the trees in the image. The high Pinnacles that are the prominent feature of the park are just to the left of the center of the image.
