Under the BLM permit number on the sign is some information about the owner of the facility. That address and phone number corresponds with Metro's police substation on the South Strip. They own another facility located on top of Gass Peak.
When I was on the summit I was looking over the facility and I noticed a marking that mentioned "Gass Peak". I didn't look it over too well, however, so I figured that this peak was, in fact, Gass Peak (which I had heard numerous times when scouring this website before my move). When I got home, however, I looked it up and realized that Gass Peak was another peak and that this peak was (as far as I could tell) unnamed.
I hope you enjoy your time in Southern Nevada. As you know by now, there are lots of places to hike, climb, and explore around here!
