## About Dexter Spring

Dexter Spring, a named spring thirteen miles out of Alamosa East in Alamosa County, Colorado, sits at around 7,500 feet. The USGS logged 68 degrees, a cool reading, and took a chemistry sample in 1984. Ownership and access are blank. It is a water record more than a soaking spot, and the name is all the identity it has.

X Road comes within a fifth of a mile; the record calls it a short walk. High, dry climate: ten inches of precipitation, a little over two feet of snow, mean temperature around 45. The record lists no campground nearby. No land unit is attached, and the road name is the only local detail.

The record favors winter, though at that temperature the water is a curiosity in any season. No fee recorded. Access is unrecorded, so ask before leaving X Road. The chemistry dates to a 1984 sample, alkaline, iron among the minerals listed. Camping would mean a drive, since nothing is on record close by.
