Staple Bend Tunnel Trail, Stone Sleepers

in Pennsylvania · centroid 60 mi from Pittsburgh

These large stones embedded in the ground were actually the railroad ties of the Allegheny Portage Railroad. They were called sleepers and were hand-cut from local sandstone. These sleepers were used on about 31 of the 36 miles of the Portage Railroad.

Stone sleepers were not used on the inclines of the Portage because the heavy stone blocks would have shifted out of place on the steep slopes. Each sleeper took about 24 hours of total work to create, from the quarry to being ready to place in the railbed. The workers made over 200,000 sleepers for the railroad.

Can you imagine making a 500 pound sleeper with just a hammer and chisel? Hard work indeed! Notice that there are two holes drilled into the top of each sleeper. Wooden plugs were pounded into these holes and then railroad spikes to hold the iron rails had a place to be driven into.

Plan your hike

Practical notes

Maps + permits: long-distance trails like this often require permits for through-hiking, backcountry camping, or specific sections (especially in National Parks). Check with the maintaining organisation listed above and the relevant land manager before booking travel.

Water + supplies: water sources vary seasonally on most U.S. trails. Carry a filter and consult current trail-condition reports — through-hiker journals (PCT-L, AT Reddit, etc.) and the maintaining organisation publish regular updates.

When to go: hiking seasons vary widely with elevation, latitude, and snowpack. Through-hikers traditionally start the AT in March-April (Springer northbound) and the PCT in late April (Campo northbound). High-elevation western trails (CDT, JMT, Wonderland) generally aren't passable until July.
