## About The (Landusky) Plunge

The Plunge, recorded as The (Landusky) Plunge, is a warm spring on Turtle Mountain off-reservation trust land in Blaine County, Montana, about forty miles from Fort Belknap Agency. The land is tribal and the access on record says unknown. The water is tepid. A 1973 USGS sample found moderately mineralized water, with no pH logged.

Six tenths of a mile separates road and spring, a short walk across ground the record does not describe. Elevation is low. Snow is light here, three feet or so a winter, in a dry year. Camp Creek Campground is seven miles off. The designation is tribal land, with the trust parcel as the unit.

Tribal land with no access status on record; get permission before going. the record points to winter and the snow is manageable. Seven miles away, Camp Creek Campground is where the row sends campers. The water is too tepid to call a soak. The chemistry is from 1973 and the temperature has no date of its own.
