Flood photos from Huachuca's Miller Canyon

The Sierra Vista Herald is running a few photos of the flood deposits coming down Miller Canyon in the Huachuca Mountains, near the town of Sierra Vista. The area was severely burned by the Monument fire, eliminating vegetation that normal slows runoff allowing it to soak in.

In addition, AZGS geologist Ann Youberg is quoted in a second article about Sunday's flash floods in the area following heavy monsoon rains.

Miller Canyon saw a 18-fold increase of sediment and Ash Canyon a 15-fold increase, according to the USFS Burn Area Emergency Response Team assessment [right, erosion hazard and sediment deposition in selected canyons in the Huachucas. Credit, Coronado Natl Forest BAER Team]
