The failure slope contains various amounts of undulating fractures with three distinct orientations. It is unbedded and largely layered (from 3-30 meters). This diamictite is a glaciogenic, non-volcanic conglomerate that is matrix- supported.

A highly fractured diamictite makes up the unstable slope.

The first step taken in the process of remediation is diagnosing the problem. People spending more time at the site maximizes the time of exposure for falling debris, which may lead to serious injury or loss of life. The location of the piers below the slope failure creates an additional risk. Two piers have been constructed at the bottom of a slope where rock and sediment commonly build up on the Creeper trail as well as the handicap-access fishing trail located below. A former road was closed off to vehicles and converted to a handicap fishing access where piers have been installed over the north bank of Whitetop Laurel Creek. The particular area of concern is known as Creek Junction, which is found outside of Konnarock, Virginia. The site is a heavily used area for outdoor enthusiasts, who commonly hike, mountain bike, fish, and/or ride horses along the converted Norfolk and Western railroad bed. New York State Thruway Authority 200 Southern Boulevard, P.O.Debris from an unstable slope along the Virginia Creeper Trail and Appalachian Trail has given rise to concerns for public safety as well as maintenance costs for those at the Mount Rogers National Recreation Area near Marion, VA. This approach provides a more accurate approximation to the equations of motion for rock and slope interaction than employed by previous CRSP versions. The new version of CRSP has been written based on a combination of Particle Flow Code and the Discrete Element Method for dynamic model simulation. Several revisions were issued in the following years, and the program has been widely used for rockfall design. The Colorado Rockfall Simulation Program (CRSP) was developed in 1987 to estimate the velocity, energy, and bounce heights of rockfall, which in turn forms a basis for selection of designs for mitigation.
