## About Mud Volcano

Mud Volcano is a roadside thermal feature in Yellowstone, Gallatin County, the Grand Loop Road a few dozen feet away, with measured water that is hot, too hot to sit in. The Park Service manages the land and access is open, roughly sixteen miles out of West Yellowstone.

Forty feet of ground separates this from the Grand Loop Road, which is to say almost none. Elevation runs around seventy-seven hundred feet. Ten-odd feet of snow falls in a year. The mean year-round temperature is thirty-four, precipitation moderate. Park Service land, national park designation.

Winter, December through February, is what the record rates best. Roadside access means the winter question is only plowing, and the park decides that. Tower Fall Campground is listed at about eighteen miles; nothing closer appears. Any real contact with the water will burn. The temperature on record is one reading; the real figure on any given day could be higher.
