Barnes Lake Hot Springs emerge at a modest 79 degrees Fahrenheit within the Tongass National Forest, maintaining temperatures just 38.1 degrees above ambient air in this remote corner of the City and Borough of Wrangell. The springs flow from federally protected forest lands managed for both extractive and conservation uses.
The springs emerge at 129 feet elevation from a landscape receiving over 132 inches of annual precipitation and 511 inches of snow, creating an extremely wet environment dominated by temperate rainforest. The spring water supports the thermal ecosystem at this low elevation near water, where ambient air averages just 40.9 degrees Fahrenheit. The backcountry location ensures dense forest surrounds the thermal feature.
