The Seminar Forest is a forty-acre tract of land located across the Juniata Gap entrance to campus. The forest, previously known as the Ritchey Property, has hiking and mountain biking trails and a restored pond. The land has been geologically assessed, surveyed for its biodiversity, studied, and simply enjoyed by students, faculty and staff, and members of the community.
In the fall of 2011, a replica Thoreau cabin was built in Seminar Forest at the base of the trailhead along Beckers Lane. The cabin houses environmental research projects that have been undertaken in the forest. The forest is a thriving environmental education center made possible by the vision and efforts of many faculty, staff, and students at Penn State Altoona.
