Steep, burned hillslope in the 2009 Station Fire.
Detailed Description
A USGS walks on a very steep, burned hillslope in the 2009 Station Fire, Angeles National Forest, California. The wildfire has removed nearly all of the vegetation from the hillslope and well-developed rills cover the ground's surface. Rills are small channels cut into the hillside by erosion processes. They have the potential to generate a large amount of sediment, which may contribute to debris-flow formation. The Station Fire burned approximately 160,000 acres from August to October 2009, including steep terrain in the Angeles National Forest. This photo was taken approximately 1 month after the fire was contained.

Postfire debris-flow hazards
Wildfires can significantly alter the way water interacts with the landscape to the extent that even modest rainstorms can produce dangerous flash floods and debris flows. Recent fires in the western U.S. have impacted hundreds of thousands of acres of steep land, much of it public, making it susceptible to increased erosion and debris-flow activity. With the risk of severe wildfires continuing to...
