## About Jardine Hot Spring

The record places Jardine Hot Spring in Lemhi County, with Salmon given as the nearest town, essentially at zero distance. The water is hot enough to hurt, at the edge of scalding, so nobody should expect to soak at the source. Owner and access status are both blank, and so is the fee field. The USGS sampled it in February 1983 and found the water close to neutral.

Spring Street is the nearest road, about a fifth of a mile away, which makes this a short walk from town. The elevation is high enough that winters are long. Snowfall averages over seven feet a season. The year's precipitation is moderate. Twin Lakes Cabin, about fourteen miles away, is the only camping that appears.

Hot enough to scald; check before touching. The season given is winter, and with the snow totals here that means planning for cold and possibly closed roads. Access is unrecorded and the spring is close to town, so ask locally before walking in. The temperature and chemistry date to 1983, old enough that conditions could have changed.
