The Slumgullian mudflow in the San Juan Mountains dammed Lake Fork, and formed Lake San Cristobal (lower left) at Lake City, Colorado. This flow was discovered by the earliest settlers to the area and is still active. Image Credit: B. Bradley. University of Colorado The slopes above streams and rivers are subjected to a variety of processes that cause them to recede and retreat from the river or stream channel. These processes, collectively called mass wasting, can be classified according to rapidity of movement and according to the type of materials that are transported. |
