In addition to its facilities in Claremont, the Robert Center directs the REC Research Station on Tioga Pass in the eastern Sierra Nevada, overlooking Mono Lake and just a few miles from Yosemite National Park. This 160-acre reserve houses  students and a supervisor engaged in summer internships, thesis projects, and field research activities.

The station is in a high hanging valley among pines and sage, a hundred yards from a large aspen grove, and adjacent to a small ephemeral stream and meadow. Nestled at 8500 feet near Tioga Pass, the station is inaccessible during the winter. During the summer, however, students use the facility as housing and a base of operations for thesis research, faculty research, and for summer internships with agencies in the area.
