A small tight limestone canyon can be found 10 miles west of Lone Mtn. The climbing is sport on sharp gray limestone. Routes are around 30' to 60'
The area has seen a lot of development so I am not sure of the current access. Drive west through a quarry off of the 215 somewhere around W. Lone Mtn. RD. Once through the quarry look South for the obvious slot canyons. Hike south over or around a small ridge into the canyon. Head South up canyon for Trench Town turn West at the junction to get to Water World.
Waterworld has some of the nicest moderate limestone climbing around. In this wacky world of chipped desperates, this beautiful slot canyon is a breath of fresh air and a great place to enjoy some desert solitude. The mining situation has created some hazardous and labrynthine methods of reaching this area that none of the guidebooks cover effectively; Las Vegas is an ever-changing landscape as the houses creep up against the mountains. I am trying to get a best-case scenario map for the hike in if you drive a compact car and a helpful desert topo for the dicey 4WD over the sketchy hill and SOFT wash. Don't miss this area-it rivals St. George's Soul Asylum for a good day of moderate, fun, very high quality limestone. My buddy Danger Dragon and I climbed all these routes in a day, had shade, and a great time. More info soon.
We were visiting from New York, wanted to try some limestone, hoped it would be sheltered from the winds that had been blowing. We had a 2WD normal (low) clearance rental car, so driving in past the quarry could not be an option for us -- even if it were legal to do it (a question I leave for lawyers local Las Vegas residents).
Some things we found out:
The climbing was interesting, and different from other rock we've tried before, in two ways: lots of rather sharp edges, and mostly vertical features. So we found ourselves doing lots of side-pulls and pinches - and being very careful with how we grasped the rock.
GPS: latitude+longitude of some key locations:

Perhaps the best way to get access is different on mid-week days from on weekends.
We tried on a mid-week day.
We tried going in thru the quarry (described in the two guidebooks). Soon a guy drove up to us and told us we couldn't walk in that way -- suggested we start instead from further north or further south.
We tried starting further south. It took us about 2.5 hours to walk in to the Waterworld climbing routes, about 1.5 hours to walk back out to our car after climbing.
We noticed that the main road west from the quarry was blocked by a very large deep pit or trench. (approximate latitude/longitude = N36.246 W115.360)
We found a new bolted route a ways east from the main set of Water World routes. Seemed to us the difficulty was around 5.7- (It made a nice warmup for the other routes we climbed at Water World.)
