## About Mosley Spring

Off Dark Canyon Road in Eddy County, around fifteen miles from Carlsbad, Mosley Spring comes up barely warm. Upper sixties. That is swimming hole temperature on a hot day and nothing more. Access is unrecorded. A 1949 sample showed a moderate mineral load of calcium, magnesium, sulfate and chloride, and nothing has been run since.

Dark Canyon Road passes within a hundred feet. Low desert under 4,000 feet, hot through the summer and dry all year. Snow hardly ever. Owner and unit are missing. Sunset Reef Campground is about nine miles off. Rain is scarce. Dark Canyon Road is the only named feature on file, and the road class says you can see it from the car.

Camping on record: Sunset Reef, nine miles. The sample is old, 1949. Confirm land ownership before stopping, because the road frontage belongs to someone. Midwinter is when the low desert is bearable. There is no reason to expect a soak at this temperature, so think of it as a landmark and a data point.
