The Class of 1908 at what was then known as the Pennsylvania State Forest Academy in Mont Alto shot its formal class photo in front of Wiestling Hall. The building, constructed in 1807, once served as a manor for Col. George Wiestling, one of the area's wealthiest iron masters. When this 1907 photo was developed, there appears to be an image of a human figure standing in the background (click on photo album to see close-up image), as if observing the men on horseback.

Wiestling died in 1891, 12 years before the forest academy's establishment. Credit: Penn State Expand Wiestling Hall as it appears today on the Mont Alto campus. The building has served as a dormitory, dining hall, classroom, administrative headquarters and possibly home to two ghosts.

One of its most famous attendees was Amelia Earhart, who enjoyed climbing onto the roof of the Sutherland Building. Some believe Earhart never left campus, as witnesses have reported hearing mysterious footsteps coming from its roof.

According to legend, after the home was built, John Conyngham accidentally -- or not so accidentally -- fell down the home's elevator shaft to his death. In the time since, students and staff have claimed to hear bizarre noises and slamming doors when the building is supposedly empty.
