Monument Geyser Basin
Monument Geyser Basin is a thermal basin in the Gallatin County part of Yellowstone, two miles from West Yellowstone by the record, and within half a mile of the Grand Loop Road. The recorded reading is near boiling. Park land, open access. Look, do not touch.
The Grand Loop Road sits four tenths of a mile out, and the basin is in the low seventy-three hundreds for elevation. The climate record gives about ten feet of snow a year and a degree or so over freezing on the yearly average. Rain and melt are moderate. Designated national park, run by the Park Service.
The climate entry favors December through February, and that hinges on the Grand Loop Road being open, which is the park's call. Indian Creek Campground, fourteen miles away, is the listed campground. Scalding water. Stand well back, on ground that holds. The water chemistry on file comes from an October 2007 sample. Nothing on the record about a fee.
A USGS site number is attached to the basin, with a water sample from October 2007 on file. That sample measured a pH a shade under neutral, and the minerals listed are sodium, calcium, magnesium, chloride and sulfate.
The water at Monument Geyser Basin is slightly acidic (pH 6.7). It is notably rich in sodium (supports circulation and skin hydration) and chloride (natural antiseptic with skin health benefits).
