About this work
The Blackhawk landslide, Lucerne Valley, California, is a lobe of marble breccia, 10 to 30 m thick, 3 km wide, and nearly 8 km long. Geologic evidence shows that the rockslide came down the gently inclined slope as a nearly monolithic sheet moving more than 100 km per hour. The accepted hypothesis is that the slide was lubricated by a layer of compressed air. At least two earlier similar but smaller rockslides have occurred in the area.
