Friday Field Photo #181: Fault Scarps on Badwater Fan
This week’s photo features a rather famous alluvial fan, the Badwater Fan just south of the tourist stop in the lowest spot in the continental United States (at -282 ft) in Death Valley National Park. The east side of Death Valley has numerous small and steep (for depositional systems) alluvial fans. These piles of sediment are aggrading as fast as they can to keep up with the basin dropping out from under them. Further evidence of the movement along the boundary fault (between the uplifting range and the downdropping basin) are the fault scarps in the photo above. Good stuff.
Here are a couple GoogleEarth snapshots of this fan.
