Hot Springs Near Hot Springs Cove
This 192°F spring in the Aleutians ranks among Alaska's hottest thermal features, far too hot for safe bathing. USGS analysis shows a high-salinity mineral profile with 1,300 mg/L chloride and 650 mg/L sodium, indicating deep geothermal circulation.
At Hot Springs Cove in the Aleutians West Census Area, the spring emerges at 100 feet elevation along rugged coastline accessible only by sea. The water remains intensely hot and mineral-rich, colored and conditioned by dissolved solids from deep subsurface circulation through volcanic rock.
The distinctive chemistry—180 mg/L calcium, 1.5 mg/L magnesium, 88 mg/L sulfate, and 40 µg/L iron—reflects water circulating deep through volcanic formations before ascending. Recent USGS measurements confirmed 92.5°C (198.5°F), virtually unchanged from standard temperature records.
Backcountry access via boat only; no roads reach this location within 27 miles. The site sits in one of Alaska's most exposed maritime environments with annual precipitation of 51.9 inches and 91.5 inches of snow. Plan accordingly for harsh weather.
