View Fact Sheet.

During the week of September 9-13, 2013, nearly continuous rainfall caused widespread landslides and flooding in the northern Colorado Front Range. The US Geological Survey Landslide Hazards Group in Golden, Colorado conducted reconnaissance from the ground and air and determined that affected areas are likely to be susceptible to catastrophic failure during rainstorms and snowmelt for several years. People should be aware of this potential hazard and use caution where traveling in the northern Front Range canyons.
