## About Maple Grove Hot Springs

Maple Grove Hot Springs, seventeen miles or so from Preston in Franklin County, Idaho, is a very hot spring, the temperature at the source far beyond scalding. Nothing can sit in that water as it comes out. The record leaves land owner and public access blank, so there is no confirmation here that visitors are welcome. There is an image attached to the record.

Oneida Narrows Road passes about three hundred feet away, so this is a roadside spring. Land unit and designation are blank on record, and so is the owner. The elevation is moderate, southeastern Idaho, and the winters drop about seven feet of snow with a middling amount of rain across the rest of the year. The campground is the only other landmark the record gives besides the road.

December through February get the nod on record. Maple Grove Campground sits a couple miles away. This water is dangerously hot, well above the scalding line, and there is nothing on file about where or if it cools, so do not touch the source. Confirm ownership and access before going; neither is recorded. Chemistry dates to 1972.
