The slopes are moderate to steep and the area is covered with colluvium . No concerns, the deposits reflect river sands and gravels. No concerns because these are good, sound glacial deposits. Substantial concerns because these deposits suggest that wind storms are common in the area. Substantial concerns because these deposits formed from down-slope movement and they may be unstable when excavated.
Lahars are accumulations of unconsolidated materials on the flanks of volcanoes.
These deposits are most often found at the base of the volcanoes and in some cases they extend many tens of miles from the cone itself. If these deposits are mapped in a region, there is significant concern for safety. They were mobilized by rocks falling from the volcano during a major earthquake. They were ejected from the caldera and could bury a town. A road-cut in Morgantown is only about 6 feet in height, yet it has cost hundreds of thousands of dollars over the years to continually repair damage done by the continued movement of the slope onto the road.
