Data obtained from six large trenches cut into various slope situations indicate that movement on the upper one third of the southeast-facing slope is extremely slow and that this portion of the slope is in a condition of stability. Movement on the lower two thirds of this slope is maintained mainly by solifluction and creep, with some areas of more or less stabilized benches. The benched features on the opposing slope are stabilized forms which originated perhaps thousands of years ago during a climate warmer than present. These features are regarded as having been formed by a process intermediate between earthflow and nonsaturated creep.
