Quizplus · Accepted Answer

The Slumgullion area of Colorado experienced a slow-moving earth flow, which is a type of slope failure where soil and rock slowly move downslope due to the force of gravity. This movement can be caused by a variety of factors, including saturation of the soil, changes in the slope angle or material properties, and earthquakes. In the case of the Slumgullion area, the earth flow was triggered by heavy rainfall and runoff from snowmelt.
