Short summary
We used high-resolution topography collected over 4 years to investigate how two watersheds in Colorado responded to the June 2012 High Park Fire and an extreme flood in September 2013. After the fire, sediment was eroded from the hillslopes and deposited in valley bottoms, and the large flood eroded much of this deposited sediment. Patterns of erosion and deposition were related to landscape characteristics, burn severity, and rainfall, which may inform future post-fire treatment strategies.
