TRF is a broadband station on Thorofare Ridge, near the Eielson Visitor Center in Denali National Park. This site is generously hosted by our partners at the National Park Service. The station was installed in 1989 and upgraded with digital broadband equipment in 2003. In 2016 the vault was replaced with a USArray-style borehole and new sensor. It is one of four seismic stations inside the park.
