Very Hot Source, Use Extreme Caution

At 184°F, the source water at Mud Springs is hot enough to cause burns. Some hot springs this hot have cooler side pools or downstream areas suitable for soaking. Always test the water temperature before entering.

Mud Springs in Pershing County is one to be careful around. The water comes out scalding, far beyond anything skin can take, hot enough to burn in seconds. The land is BLM, Black Rock Field Office, with public access on record as open. Lovelock is the nearest town, nearly sixty miles off. Come to watch the steam.

Location
46 miles from Cold Springs, NV

A few hundred feet of walking from the nearest track gets you there; the record does not identify that track. The ground is low by Nevada standards, under four thousand feet, and dry. Snow arrives in modest amounts through the winter, under two feet in a typical year, with ten inches or so of moisture in total. No campground is on file.

December through February are the months listed as best. Stay well back from the source. A water sample from the mid 1960s showed high dissolved solids, sulfate and chloride among them, and nobody has updated the chemistry since. Open access, no fee listed. Lovelock is a long drive back for anything you forgot.

Heat Below
86 milliwatts per square meter of heat flow

That's about 1½ times the US average of 65. It's higher than at 25% 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.
