AZGS geologists assessed paleo- and recent debris flows in Organ Pipe Cactus National Monument, as part of our ongoing geologic mapping of the area in partnership with the National Park Service. Ann Youberg took this picture of debris flow deposits formed in 2008.
This area of the Monument has been off limits the past year due to concerns over drug smugglers in the area, but the NPS provided security escorts to the AZGS team.
