Mud Pot: Not a Soaking Spring

Wister Mud Pot is a mud pot, not a traditional hot spring. These geothermal features can be extremely dangerous. Boiling water, toxic gases, and unstable ground are common hazards. Do not attempt to soak.

Wister Mud Pot is what the name says, a mud pot near the Salton Sea in Imperial County, about four miles from Niland and well below sea level. The thermometer reading on record is 100 degrees. It is mud, though, so the number describes something to watch. Land is held by the local irrigation district, access open, and one photo sits in the record.

Location

Davis Road passes within eighty feet, so the mud pot is a drive-up stop on ground more than two hundred feet below sea level. Rain totals three inches in a typical year, no snow, an average temperature near 77 that makes summer ferocious. The land unit on record is the Salton Sea irrigation district, and no campground is listed within range.

Winter, December through February, is the listed time to come, which anyone who has felt an Imperial Valley July will understand. No fee, open access, roadside. Nothing on file describes a pool or a path, so expect to view it from the road. Niland is the closest place with a name on file, four miles off.

Heat Below
118 milliwatts per square meter of heat flow

That's about twice the US average of 65. It's higher than at 70% 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.
