Springs and Seeps

Seeps are small, ground water springs that bubble to the surface through small pores. The amount of discharge from a seep is not as evident as from a spring. Seeps and springs at the Summit Unit near Cresson, PA form the headwaters for Blair Gap Run to the east, and to the lesser extent, Bradley Run to the north. Seeps existing at the Staple Bend Tunnel Unit are fed from collapsed mines and have high metals content, resulting in the formation of iron mounds on park property.

Railroad track attached to a 'sleeper'

When the Portage Railroad opened on March 18, 1834, it was a single track line. The rule was when 2 drivers met the one who had passed the center post had the right to go on. The other driver had to back up. Some sat nose to nose until a magistrate determined who got to the center first.
