Healy (HEAL) is a terrestrial NEON field site located in central Alaska, 120 km (75 mi.) southwest of Fairbanks and at the northern border of Denali National Park. The 45.6 km2 (11,300 acre) site is managed by the Alaska Department of Natural Resources. It sits at an average of 678 m (2224 ft.) in elevation and is situated in a high-elevation, glaciated valley where the dominant vegetation consists of dwarf shrubs and sedge meadows. This valley experiences widespread permafrost thawing, making it a valuable resource to understand how other permafrost systems in Alaska may experience and react to thawing in the future. The site is open to the public for recreation including hunting, berry picking, snowmobiling, and dog sledding. HEAL is one of the four sites (three terrestrial and one aquatic) located in the NEON Taiga Domain (D19), which comprises Alaska’s interior and the Alaska Peninsula.
