Lower Jerry Run is a small stream draining into Sinnemahoning Creek. The area not only contains a remnant stand of old growth white pine and hemlock , but it is also a reptile and amphibian protection area. The entire area is relatively inaccessible, but the old growth is found on a northeast-facing slope at the upper (south) end of the watershed, in the forks of Lower Jerry Run. This is a challenging and remote area visited only on foot. You can go all day without seeing another vehicle on the narrow dirt roads or another person in the forest. Solitude is almost guaranteed. Be warned and go prepared with topographic maps and compass. If worse comes to worst and you get thoroughly lost, go downhill. Eventually you will reach the valley of the Sinnemahoning Creek.

Access Details

From Sinnemahoning travel east on PA Rt 120 for approximately 0.6 miles. Turn right (south) on Wykoff Run Road and in just a short distance turn left onto Jerry Run Road (narrow, rough areas). Follow this about 7 miles to a T at Three Runs Road. Turn left (northeast) and go approxiamtely 1 mile to Jerry Ridge Trail. This is an old woods road on the left. From this point you may want to walk if your vehicle has low clearance. About 0.25 miles down the road turn right into the parking lot and follow the orange blazed trail into the Natural Area.
