Panoramic virtual tour of the CRREL Permafrost Tunnel
The Fox Permafrost Tunnel, now almost 50 years old, will be expanded in the next few years to stimulate research. The tunnel, 10 miles north of Fairbanks, Alaska, was excavated in the 1960s by the U.S. Army Cold Re-gions Research and Engineering Laboratory (CRREL) and U.S. Bureau of Mines. The expanded tunnel will more than double the current tunnel's length and is designed to directly incorporate research needs. Some design features include: a) detailed 3D map of complex permafrost features between the two tunnels, b) extensive base-line mapping and sampling, c) side rooms to allow for permafrost warming experiments, d) boardwalks and gantry above tunnel for test geophysics and re-mote sensing. In addition to the expanded tunnel, new facilities will be built on site, including laboratories, offices, cold rooms, and a learning center.
