The Toolik Field Station is located in the northern foothills of the Brooks Range in northern Alaska on the southeast shore of Toolik Lake (68°38’N, 149°36’W, elevation 720 m, 254 km north of the Arctic Circle). This location affords access to three major physiographic provinces of Alaska: the Brooks Range, the Arctic Foothills and the Arctic Coastal Plain. Toolik Field Station also serves as a base for researchers working along the ecological transect connecting tundra to boreal forest along the Dalton Highway between Prudhoe Bay and Fairbanks. Toolik Field Station is operated and administered by the Institute of Arctic Biology at the University of Alaska Fairbanks.
