Arizona Geology Blog: Post-fire flooding and Debris Flow Impacts in the Museum Fire burn
by Rebecca Beers (AZGS Research Scientist)
On the week of July 12, 2021, torrential rains deluged the 2,000 acre July 2019 Museum Fire burn area, one mile north of Flagstaff; more than 2 inches of rain fell on 13 July, with 1.06 inches falling in less than 15 minutes. The following day an additional 1.22 inches of rain fell. The blog post includes a 30-second video of the flash flood on Elden Lookout Road by Enrique Rubio.
The rain produced debris flows and generated flash floods in the burn area and environs. AZGS geoscientist Rebecca Beers began her study of the Museum Fire zone while a graduate student at Northern Arizona University. In the Arizona Geology Blog, Rebecca shares her recent observations and her research goals.
