## About Hot Spring

Despite the name, this Hot Spring off Owens River Road comes out barely warm, under seventy degrees on the sample in the record. It sits on Bureau of Land Management ground in the Bishop Field Office, about eleven miles from Mammoth Lakes, with access listed as Open. What stands out is the mineral load: the water carries a heavy dose of dissolved solids.

Owens River Road is the nearest road, roughly a thousand feet away, so figure on a short walk across BLM land. The elevation is around seven thousand feet, high desert on the east side, with winters that pile up six or seven feet of snow. Beyond that the year is dry. Convict Lake Campground, about eight miles out, is the camping listed.

The USGS carries this spring as a numbered site and sampled it in the summer of 1993, finding calcium, magnesium, sodium, sulfate, chloride and iron in the water.

Midwinter rates best on file. The temperature and chemistry come from a 1993 sample, so the water may have changed since. Nothing here is warm enough to call a soak. Access is open under BLM management and no fee is recorded. The USGS lists the site.
