Standing Stone Trail: Mapleton to Greenwood Furnace State Park Map

Located deep in the Appalachian Mountains lies this incredible, lesser known 80-mile hiking trail. Commonly referred to as the SST, the Standing Stone Trail provides endless options for day runs, and a few daring ultrarunners attempt the entire trail each year.

Description

The trail is also part of the 1,800-mile long Great Eastern Trail, an alternative route to the Appalachian Trail. When completed, the route will include the Pinhoti, Cumberland, Tuscarora, and Allegheny Trails - among many others.

According to www.standingstonetrail.org, "the valley to the west of the SST is the historic Native American trail called the Standing Stone Path, which connected Fort Littleton with Fort Standing Stone, today called Huntingdon." Over the last two centuries, the area has been utilized by countless coal mining and logging operations, the remnants of which can be seen along the way.

This segment holds one of the most-recognized landmarks on the trail: Thousand Steps. A short spur from the road makes this one of the most visited sections of the entire trail. According to standingstonetrail.org, "Located in Jacks Narrows near Mount Union, the steps were built in the 1950s by quarry workers who cut away a large slice of Jacks Mountain to quarry the ganister stone used to make silica bricks. The quarry opened around 1900, with its heyday in the early 1920’s. Local factories each day turned out nearly a half million bricks to earn Mount Union the title of Bricktown USA."

After passing several overlooks, including Shorbs Summit, the trail meanders down to a road crossing. Ahead, you're welcomed with a gentle traverse along the western slope of Stone Mountain.

An incredible stretch of trail lies ahead as you enter the Rocky Ridge Natural Area. According to standingstonetrail.org, "The region features a rare wildflower called obolaria, which grows only in one other place in Pennsylvania. The endangered putty root orchid, along with hundreds of lady slippers also can be found here." This area is also frequented by rock climbers due to the unique "standing" sandstone rock formations.

The final, and most challenging ridgetop traverse lies after Allensville Rd. Several rocky vistas make this a popular area for day hikers and two spur trails from Turkey Hill Road created even more options for running loops. The trek across the ridge is arguably the most memorable portion of the trail. Many of the rocks have been positioned to create a path as it traverses from Stone Mountain Hawk Watch to Greenwood Furnace.

The northern terminus for the SST lies in Greenwood Furnace State Park. Before its time as a state park, the furnace outlasted any of its predecessors. To this day, many of the original structures can still be seen.

If completing a longer thru-run, take the opportunity to resupply at concession stand in the park. While this is the official northern terminus of the Standing Stone Trail, the Greenwood Spur of the SST lies ahead and connects to the Mid-State Trail at Detweiler Run Natural Area.
