Narrative:

The van sant airport; erwinna; PA is located on a knoll having the crest near the middle of the main runway 6/24 [7/25] which is utilized by powered aircraft and gliders. Recently; runway 6/24 was improved by the removal of some of the crest of the knoll; however this work was done such that there is a sharp edge between the northern edge of the middle one third of runway 6/24 and the terrain north of the runway which comprises a ramp/tie down area and the extension of glider runway 5/23. This sharp edge prevents a low wing glider from crossing that area and thus clearing the runway 6/24 [7/25] to the north after landing or during an aborted takeoff. Furthermore; the side slope of runway 6/24 having the northern side higher than the southern side precludes the possibility of a low wing glider lowering a wing during a cross wind landing or takeoff when the cross winds are from the north/northwest. Gliders landing long on runway 23 have the risk of dropping off (at perhaps slow speed) the sharp terrain transition between runway 6/24 and extended runway 23. Another risk is that runway 6/24 continues to be on a shallow knoll such that a glider that lands and stops near the center of runway 6/24 cannot clear the runway due to the terrain sharp edge to the north and the drop off of the terrain to the south of the runway precludes that option; furthermore a glider must roll beyond the area of sharp terrain transition to clear the active runway; if the glider does not have sufficient energy to do so; or the pilot does not foresee this safety issue; the glider would be stopped possibly on the blind side of the hill so to speak. Van sant is an uncontrolled airport; having a unicom frequency which some pilot utilize and some do not. It is suggested that the sharp terrain transition along the northern edge of runway 6/24 be removed to create a rounded shallow transition of terrain such that a low wing glider can safely transition to clear the runway after landing or an aborted takeoff. If the knoll of runway 6/24 can be further removed; such that a low profile aircraft such as a glider; could be seen from any position on runway 6/24; that would be an additional safety enhancement.
