Baranof Warm Springs (thermal mineral springs)
# Baranof Warm Springs (thermal mineral springs)

Baranof Warm Springs are a series of ten geothermal mineral springs located in the small community of Baranof Warm Springs in Sitka, Alaska. The springs are surrounded by the Tongass National Forest.

## History

The springs were originally used by the Tlingit of Angoon. Settlers later discovered the springs in 1891.

## Geography and geology

The springs are located on the north side of the Baronof River approximately 500 feet downstream from the Baranof Lake inlet. The springs flow from deposits of gravel, silt and quartz diorite boulder and bedrock.

## Water profile

The hot mineral water emerges from the ground at a temperature of 124 °F/51 °C. The water composition is sodium carbonate type, with large proportions of silica. The sulphurous hot mineral water flows from the source into several rock-lined soaking pools where it is cooled to between 108 °F and 110 °F. There are also three wooden roofed rooms supplied with the hot spring water.
