Hunter's Hot Springs, Hot springs in Lake County, Oregon.

Hunter's Hot Springs features naturally heated mineral-rich waters reaching temperatures between 185°F and 205°F, emerging from underground geothermal reservoirs across approximately 40 acres of alkaline pools and channels.

Discovered in 1832 by Hudson's Bay Company trappers, the springs were later developed by Minnesota land developer Harry Hunter in 1923 into a health resort that operated through multiple ownership changes over nearly a century.

Locals still call the springs Hunter's Hot Springs, though the 2000 owner renamed the resort Geyser Hot Springs; the USGS recognizes only Hunters Hot Springs and the variant Geyser Hunters Hot Springs. Harry Hunter organized the Hunter's Chlorine Hot Springs Club in 1923, with H. A. Utley as first president and Dr. H. G. Kelty as general manager, to run the site as a therapy and rest resort.

The resort operates a motel, lounge and restaurant, and guests can use the 104°F (40°C) mineral pool. The Old Perpetual viewing area is open to the public. The springs sit about 2 miles (3 km) north of Lakeview in Goose Lake Valley, reached by road from town.

Old Perpetual formed by accident: when Harry Hunter drilled three wells in 1923 to boost the springs' flow, all three erupted as geysers. Two soon stopped, but Old Perpetual kept erupting every 40 to 120 seconds until 2009, then resumed by May 2015.
