Great Allegheny Passage Hike 25

Rockwood to Confluence

Now headed southwest, the Great Allegheny Passage continues to hug the Casselman River. After six miles you pass the village of Markleton. Once a hub of activity, it is now a small cluster of houses and a post office (ask for water here). Next is the Pinkerton Tunnel, restored in 2015. Fort Hill is passed unnoticed to the north and the segment ends at the town of Confluence after two grand crossings of the Casselman.

Explore the PHT

Once there was a pulp mill here that was said to be the largest of its kind in the world. This was one of many "company towns" in the area, in which a company (usually related to logging or mining) laid out a town right at the work site. Houses were leased by the workers and most left when an operation closed down. Markleton included 15 houses, a store, a church, and a stop on the B&O Railroad.

Pinkerton Tunnel
This is a fascinating place to linger. The trail crosses a long trestle toward Pinkerton Tunnel, followed by a second even longer trestle. The tunnel was restored in 2015, and trail users can still access the 1.5 mile detour around the Pinkerton Horn; rail was laid in 1879 by the B&O after the tunnel collapsed during a fire. The track was used until 1885 when the B&O rebuilt the tunnel with brick. This was an unusual place for track workers because the two railroads, Western Maryland and B&O, had side-by-side tunnels. This made it sound as if a "ghost" train was in your tunnel because it was literally only a few feet away behind a wall when on the other line.
