## About Gas Vent

This one is listed on the record as Gas Vent, a thermal point in Yellowstone National Park, Gallatin County, Wyoming, a short walk off the Grand Loop Road. There is no measured temperature, only the label hot. The water sample on file is strongly acidic. West Yellowstone is the nearest town at around three miles by the record. National Park Service land, open to the public.

The Grand Loop Road passes about a tenth of a mile away, which makes the vent a short walk in. Elevation is close to 7,450 feet. Cold, snowy climate on file, around a hundred and thirty-seven inches in a year. Park Service ground inside Yellowstone. Nothing on record describes the ground around it.

No season is recommended on the record, and the snow total means winter is a serious matter. Short walk, public access. Indian Creek Campground, around ten miles away, is the closest camp on record. A 2006 sample showed very acidic water and nobody has measured the temperature, so keep away from it and check current park guidance for this stretch of road.
