This shady cliff is home to several quality lines including a few moderate routes. The climbing consists of gray slabby rock and steeper orange rock. The classic of the crag is Mary Jane, a 5.11b that climbs a pocketed corner and pulls through a bulge. This cliff is a great destination to escape the Vegas heat, and has a short approach, even by Mt. Charleston standards.
Getting There
Take S.R. 157 from US-95 all the way past the Mt. Charleston hotel into Kyle Canyon. Follow this road as it winds up the hill until you encounter a sharp left-turning bend in the road. Immediately before this bend, turn right off of the road onto Echo Rd. and continue uphill and follow the signs toward the Mary Jane Falls turn-off. Park on the north side of the lot by the outhouse. The approach to Mary Jane follows the trail up the canyon for about five minutes. On the left (southwest) side of the canyon just above the wash you will see the clean wall of the Mary Jane Crag. Cross the wash, and hike up the short trail/switchbacks to the base of the cliff.
The Classics
Mountain Project's determination of some of the classic, most popular, highest rated routes for Mary Jane Cliff:
It's hard to trust a guy who doesn't get the name designations of major highways correct. First of all, it's S.R. 157, Not "57", (a.k.a. Nevada State Highway 157) that leads West into Kyle Canyon. This state highway deadends in the canyon after approximately 22 miles from the turn-off of the other major highway designation mistake.
"I-95" (a.k.a. Interstate Highway 95) is one of the most famous Interstate highways in the country, but it doesn't come within over two-thousand miles of Nevada. It runs the length of the eastern seaboard from Maine to south Florida, including New York City, Washington DC, Hilton Head SC, Savannah GA, and Jacksonville, Fort Lauderdale and Miami, Florida. Does any of that sound like Nevada?
The correct name for the highway in question is "U.S. 95" (a.k.a. United States Highway 95), which leads North out of Las Vegas, NV. I don't know where the poster is from, but I'm guessing southern California. I've found it endemic for people from southern "Cali" to mistakenly refer to any divided, multi-lane, limited-access highway as an "Interstate".
Not sure who you are Braveheart, but you obviously missed guideline #1- Don't be a JACKASS!
If you'd have read the disclaimers I posted on the main Charleston page about where all the information came from, you'd have noticed that I posted the descriptions from the Islands in the Sky guide. If anyone wants to post corrections for me to make just shoot me a PM.
