Assessing rapid erosion after the Horseshoe 2 wildfire

Debris flows are a serious hazard after wildfires and AZGS is working with the USGS and Forest Service to develop better predictive techniques and models. AZGS geologists Ann Youberg and Joe Cook recently went back country with Forest Service personnel to Emigrant Canyon at the north end of the Chiricahua Mountains to assess post-fire erosion following the 2011 Horseshoe 2 Fire.

The results of their assessment was published today in the online Arizona Geology magazine.
