BETA PHOTO: Big Sleep Dome as seen on the drive in on Browns M...
This massive dome is a dream of easy slab climbing on incredibly grippy high-quality granite. The summit is a surprisingly prominent pinnacle for a dome like this, and offers expansive views of Southern Yosemite, the Minarets, the Eastern Sierras, north along Shuteye Ridge to the Shuteye Peak fire lookout, and south toward Crocodile, Voodoo, and the Eagle's Nest.
The approach and deproach are great adventure from start to finish. From North Fork, follow Mammoth Pool Road (also known as Minarets Road and Rd. 225, most often signed as "Rd. 225") about 22 miles. Drive about 1 mile past well-signed Rock Creek Campground, and turn left on Browns Meadow Road (Mostly signed as "7S02"). Drive about 8 miles, being careful to stay on 7S02, which sometimes means just staying on the most well-traveled road, since some roads are poorly signed or not signed at all. After about 8 miles, turn right on 7S02K (signed with a small but legible signpost). Drive about a mile (or walk it if you have thin tires) to a really nice campsite in the tall trees. There is another approach (an earlier right turn off of 7S02) in the guidebook, which I know nothing about.
A giant boulder called the "Petrified Elephant" will be visible to the east. You can't miss it. Walk toward this boulder's right side. Grahm Doe's new guidebook shows you walking straight past this to the big slab, but you don't. Turn right at the Petrified Elephant and look closely for the "trail" that leads to the big open slab. You can't see the slab yet. At the slab, follow cairns to the other side of the slab until you are below the center of the southwest face of Big Sleep. Here, a trail follows a gully up to the toe of the slab, which is about 10 feet left of the start of Afternoon Nap. All but a couple of climbs start to the left of where you meet the formation.
I've centered the map on the spot where you'll meet the rock at the end of the trail.

A fantastic and easy romp up a giant dome, this climb seems very civilized compared to the approach and descent. Begin by getting to the rock (20 minutes if you know what you're doing, up to a couple of hours if you don't) following the directions on the "Big Sleep" page. From the end of the trail, scramble up and right about 20-30 feet. You will see a bolt about 20 feet up. This is where the route starts.All pitches are 60 meters, so don't tie in with a long tail, and don't plan on using an...[more] Browse More Classics in CA

Descending Big Sleep involves either rapping Afternoon Nap, or walking off to either the right or left after continuing to the summit of the dome. If you choose to rap, be mindful of the fact that you'll be rapping a popular route that includes a hanging belay at the start of the last pitch. Be courteous to parties ascending this route.
Walking off takes you to other domes and walls on your way back to where you parked. Walk off to the right and you can access Voodoo, the Crocodile, and I imagine other formations. I haven't gone this way. Walking to the left is an easy way to get to Midway Dome, 12 O'Clock Rock, Little Sleep, and whatever you have the energy to get to nearby.
I have no descent beta for the walkoff to the right. For the walkoff to the left, head toward Midway Dome, then begin to drop down the gully between Big Sleep and Little Sleep. For a while, you'll stay near Big Sleep, then you'll trend skier's right toward Little Sleep, always following the path of least resistance through the brush and boulders. About 200 feet above Little Sleep, as you start to get into terrain that looks really rough, scan the bottom of the gully, which is now filled with giant boulders. If you are attentive, you'll see a cairn or two, which will lead you to a trail that has been gardened to a width of about two feet and cairned by some wonderful soul. This trail leads to the slabs, where you can get back to the campsite at the end of 7S02.
