| Location description: |
Vault Creek (VC) permafrost tunnel, located 20 km north of Fairbanks, in the discontinuous permafrost zone (http://gtnpdatabase.org/boreholes/view/609/). The tunnel, which is about 40 m deep and 220 m long, is situated on a north-facing slope and was excavated in 1990 by a local private gold miner. The entrance is secured by a 30-m-long steel tube, making the uppermost part of the section inaccessible. According to Schirrmeister and others (2016), it is the deepest and longest permafrost tunnel available for permafrost research in Alaska. Fieldwork was conducted at the tunnel in April 2004 and May 2016. At the site, permafrost reaches up to 120 m in thickness and is relatively warm with a mean annual ground temperature of -0.7 C. |
