## About Hot, On Lamar River

The record names this one Hot, On Lamar River, a USGS-style label for a thermal point on the Lamar River in Yellowstone National Park, reached off the Northeast Entrance Road. No temperature is on file, only a note that the water is warm, so there is no soaking claim to make. It is a hike of nearly two miles from the road, inside the park, and access is listed as open.

Park Service land at around 6,800 feet. The walk in starts from the Northeast Entrance Road and runs about two miles, by the record's measure. Winter snow here is deep, ten feet and then some. Slough Creek Campground is the nearest camping on record, ten miles away.

No best season is listed, and neither temperature nor chemistry is on record. What the record does say is that it is open and a hike in. Plan for summer given the snow, and treat the water as unknown: test it before assuming it is warm enough, or cool enough, for anything. Yellowstone's rules apply.
