State game officials say climbers have contributed to endangered species habitat degradation in several prominent climbing areas.
As of April 5, climbers in southwest Pennsylvania’s Fayette County have to drive farther to get on the rock. The Pennsylvania Game Commission (PGC) found that increased climbing on two parcels of state-owned land in the county damaged plant and animal habitats.
State Game Lands 51 and 138 are home to multiple popular sandstone crags. The locations sit on the Youghiogheny River in rural Ohiopyle and near Laurel Canyon further west. Bouldering at Casparis and Coll’s Cove is now closed, as are the Lost Crag and Rob’s Knob, among other locations.

Southwest PA Rock Climbers Lose Over 30% of Routes
Total closed climbing resources amount to over 250 known routes and boulder problems, per Mountain Project. For climbers, it’s a significant loss in an area without a whole lot of stone; Mountain Project lists just 714 total routes (including the recent closures) in southwest Pennsylvania.
The loss is almost certainly even higher between the listed areas, less-known crags, and prospected but unclimbed locations. But the PGC asserted that the now-closed formations host critical habitats for several rare, threatened, or endangered plant and wildlife species.
Increased climbing, the commission stated, has worn away lichens and moss on rock faces. It also said climbing had eroded landings at the bases of rocks, stripping away vegetation, woody debris, and leaf litter.
The changes, it found, degraded habitat, impacting the reptile, amphibian, and mammal species that use it.
