On the upper part of the mass movement, rock fall material is exposed at the scarp face
and is detached from the bed rock where it moves in the direction of down slope (Fig.6c).
Some 120 acres out of 800 at Slimbridge are open to the public on a site which lies in a lowland area between the scarp face
of the Cotswold Hills and the Severn Estuary's upper reaches.
During subsequent monitoring from 1997-1999, a scarp face
(a cliff caused by soil displacement) developed at an elevation of 493 meters (1,615 feet), facing toward the US 58 ramp.
Similarly, at Union City west-dipping reflectors beneath the scarp face
appear truncated on the west near the base of the scarp, and auger data suggest a fault.
Out of about 24 Nautile dives, 13 were focused on the scarp face itself.
The figure below shows the total magnetic field recorded during three vertical traverses up the Blanco Scarp face. The most outstanding feature of these profiles is the dramatic increase in the magnetic field at approximately 3,400 meters depth.
Researchers have detected what look to be ice streams flowing up to, then along, the scarp faces
. In one location, nitrogen ice appears to be flowing into an ancient crater an impactor punched into the edge of the highlands.
