Dangerously Hot, Not Safe for Soaking

Quagmire Group reaches 203°F, far above safe soaking levels. Contact with this water will cause severe burns. Look for cooled downstream pools or view from a safe distance only.

Quagmire Group is a set of hot springs in Yellowstone, about a half mile off the Grand Loop Road in Gallatin County. The temperature on file sits at the boiling point for this elevation, so nothing here is for getting into. West Yellowstone is the nearest town listed. Open park land. A USGS site number is attached, which means someone has measured it.

Location

The approach is short, a walk of around half a mile starting at the Grand Loop Road. Elevation is a little over seven thousand feet, and the climate on record is cold, with an average in the mid thirties and a snow season that piles up close to twelve feet. Precipitation is moderate. Yellowstone National Park, managed by the Park Service.

Boiling water. Keep to established paths and do not test the edges. The winter months come up as best on record, which in this snow country means over-snow travel. Indian Creek Campground is the nearest camp listed, but it is more than twenty miles off. No fee is on file.

Terrain

Aircraft with laser scanners measured this ground to within inches. The scan strips out trees and buildings, leaving the bare shape of the land around Quagmire Group.

Seen From Space

Landsat's thermal camera passed over on a clear winter day, December 30, 2023. This spring's heat shows up from about 440 miles up. The brightest yellow marks the warmest ground, roughly 8°F warmer than the land around it.

Drag to compare. The view is about 2½ miles across, and each thermal pixel covers roughly 300 feet of ground, so individual pools blur into one warm patch.

Heat Below
142 milliwatts per square meter of heat flow

That's about twice the US average of 65. It's higher than at 90% of the springs on this site.

Heat flow measures the warmth working its way up through the ground from deep inside the earth. Where it runs high, rain and snowmelt that seep down through cracks in the rock come back up hot.

Quagmire Group sits at 7,300 feet above sea level, way above the mile-high mark. You may not feel the altitude strongly, but hot water still dehydrates you faster at elevation. UV is about 29% stronger than at sea level, so bring sunscreen and drink more water than you normally would.
