A typical midslope road at the H.J. Andrews Experimental Forest in Western Oregon.  Note very high cutbank along this road segment.  These cutbanks often intercept subsurface flow during storms.

Examining road surface runoff on a road in Watershed 3 at the H. J. Andrews Experimental Forest.  Runoff from this road segment is diverted to the downslope side of the road and has gullied the fillslope.

Runoff in a roadside ditch in Watershed 3 at the H. J. Andrews Experimental Forest during a rain on snow event.

A road-related landslide at the H. J. Andrews Experimental Forest. 

This is a photo of a debris flow from Watershed 3 at the H. J. Andrews Experimental Forest during the February 1996 flood.  The debris flow initiated as several landslides on steep slopes and roads within Watershed 3.  The gaging station and much of the main access road to the Andrews Forest were destroyed by the debris flow.  photo credit:  Al Levno.

This landslide was initiated on a steep slope and intercepted a midslope road (note person for scale standing on the midslope road to the left of the slide scar).  The road material was entrained in the slide and hillslope material below the road subsequently failed.
