I went here last weekend and was pleasantly surprised! It's a great little attraction. It's about an hour north of Las Cruces so it's a bit of a drive but it's very pretty and well worth it. I was a little surprised by how few ruins there were when I initially drove up but upon a little exploring you realize there's more than meets the eye.
We drove right up to the school house and were greeted by a wonderful employee who knew a lot about the site and took the time to tell us stories and answered all of our questions. I was actually surprised by how much information the school house had. It's a great little museum.
Some of us went out on our own and explored the ruins after the museum. It was a beautiful day and a great walk. The trails are clearly marked and there were little tons of little surprises along the way. Be on the look out for an endless pile of tin cans that trails off into the dessert and a similar pile of glass bottles behind one of the houses. We really enjoyed seeing the mine (from a distance) and exploring the houses.
I definitely recommend this site for history lovers or those that are enamored by the (recent) wild west!
