Gas Vent, the third point on the record by that name, is a backcountry point in Yellowstone, more than six miles off the Norris-Canyon Road, Gallatin County, Wyoming. Labeled hot, no measured temperature. No water sample, no photo either. Something like nine miles lies between it and West Yellowstone, the nearest town on file. National Park Service land with open public access, though getting there means a backcountry trip.

Location

Backcountry the whole way. The nearest road, Norris-Canyon, sits 6.5 miles off, and nothing anywhere says how a person would cover that distance. Elevation runs around 8,200 feet. Snowfall comes in near a hundred and forty five inches a year, with the yearly average temperature down in the low thirties. This is Park Service land.

There is no best-months entry on the record, and the snow total makes winter a poor bet. The park's backcountry rules apply. Indian Creek Campground is about twenty miles away, the closest on file. Temperature is unmeasured, so treat the vent as dangerous until proven otherwise, and do not plan a soak 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
126 milliwatts per square meter of heat flow

That's about twice the US average of 65. It's higher than at 77% 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.
