About This Trail

The David S. Ammerman Trail follows a former Pennsylvania Railroad branch for about 11 miles across Clearfield County, from Clearfield through Curwensville to Grampian. The crushed stone surface is mostly smooth, and the grade features a steady climb of about 400 feet mostly toward Grampian. The corridor keeps company with water the entire way: the West Branch of the Susquehanna River out of Clearfield, then Anderson Creek and Kratzer Run toward the western end. Old railroad bridges, farmland, and stretches of woods break up the miles, and Curwensville sits near the midpoint with parking and services. Trailheads with parking sit in Clearfield, at Uncles, at Arnoldtown Road, at the NARCO lot, and in Grampian.

RailTrailWx TIPS

David S. Ammerman Trail

Your comfort. Prognosticated.

  • Grampian sits about 400 feet higher than Clearfield, so westbound is the gentle uphill and eastbound the coast home. The steepest sustained stretch is just over 2 percent near the Grampian end. It's also where the trail's surface is the roughest and may require caution, especially going downhill.
  • The corridor runs east-northeast to west-southwest, so a west or southwest wind is a headwind on the climb toward Grampian and a tailwind on the return to Clearfield.
  • About three quarters of the trail runs below a north-facing valley wall. That keeps things a bit cooler and more humid through much of the day.
  • Roughly half the trail is under tree cover, with a third in deep shade and the rest open through the farmland stretches near Curwensville. Expect real contrast between shaded and open sections on a hot afternoon.
  • The trail hugs the West Branch of the Susquehanna out of Clearfield, then Anderson Creek and Kratzer Run toward Grampian. Cold air pools along the water on clear nights, so early starts often begin in fog and chill along the river.

Trivia

  • The corridor was part of the Great Shamokin Path, a route used by the Lenape and Mohican before any railroad was built.
  • Trains on this line hauled coal, quarried stone, and clay, and the clay fed the many brickyards that once lined the route.
  • The Tyrone and Clearfield Railroad was chartered on March 23, 1854, and the Pennsylvania Railroad leased it from the day it started running.
  • The Pennsylvania Railroad foreclosed on the Tyrone and Clearfield in 1867 and reorganized it as the Tyrone and Clearfield Railway.
  • The Clearfield County Rails to Trails Association bought the abandoned line from Conrail on July 30, 1992.
  • David Ammerman, the trail's namesake, was a lawyer of 40 years who served as the association's solicitor and pushed the rail trail idea for two decades.

History

The Great Shamokin Path carried Lenape and Mohican travelers along this corridor before any rail was laid. The railroad came with the Tyrone and Clearfield, chartered on March 23, 1854, to open the coal and timber country of the Allegheny Plateau. The Pennsylvania Railroad leased the company from the beginning of operation. In 1867 the Pennsylvania foreclosed on it and reorganized it as the Tyrone and Clearfield Railway. The line pushed on past Clearfield in the late 1860s and 1870s, and several railroad bridges from that era still stand along the trail. Its trains carried coal and quarried stone toward the East Coast along with clay for the many brickyards that grew up along the route. Traffic faded, and the branch was abandoned. In January 1991 local residents formed the Clearfield County Rails to Trails Association as a nonprofit corporation, with attorney David S. Ammerman as solicitor and driving force. On July 30, 1992, the association bought the abandoned line from Conrail. The first stage, 5.3 miles from Clearfield to Curwensville, was completed in 1996. The second stage, 5.2 miles from Curwensville to Grampian, followed in 1998, and a ribbon cutting officially opened the full trail on October 4, 1998. Ammerman died in July 2010. In 2011 the association renamed the Clearfield to Grampian Trail the David S. Ammerman Trail in his memory.
