Hi: I thought it might be nice to summarize the trip up the Dreaded Sand Hill, which one climbs between Crabtree Pass and Discovery Pinnacle.
http://good-times.webshots.com/photo/2153554920061435028ktypaqA great way to access Mt. Whitney is from the Horseshoe Meadows area. If one is interested in a trail, one can hike through lower Rock Creek, Guyot Pass, Crabtree Meadows and up the west side of Mt. Whitney. Although I have not gone that way, I hear it is a very nice route.
An alternative is to start at Horseshoe Meadows (using either New Army Pass or Cottonwood pass) and hike to Soldier Lake. From there hike cross country through the scenic Miter Basin, past Sky Blue Lake to Crabtree pass. At Crabtree pass one can either climb the Dreaded Sand Hill to Discover Pinnacle,

http://www.abovecalifornia.com/routes/intro.php?id=2Route up the Dreaded Sand Hill:
1) Standard route is to drop all the way down to the upper Crabtree Lake and then climb straight up the sand hill....one step up and 1/2 step back etc. Written reports have placed it as a miserable 4 hours up to Discovery Pinnacle plateau.

Bob R. told me you could not stay on the top of the ridge from McAdie to Discovery Pinnacle, but it was also unnecessary to drop all the way to the lake.
http://good-times.webshots.com/photo/2867068520061435028fsvNLeI will summarize this route.
Start at the right side of Crabtree pass (if you are coming up from Sky Blue Lake). This is on the east side. Work your way around the Cirque beginning with the large boulders that make up the western/ Northwestern base of Mt. McAdie.

You either need to climb up about 100-200 feet toward Mt. McAdie as you work your way around or you need to drop down about 50 feet. If you take one of these two options the climbing is not difficult. The traverse over or under or through these large boulders doesn't last long...maybe 500 hundred feet or so.

http://good-times.webshots.com/photo/2468501000061435028gOQSKqAs you approach to northeast corner of the cirque, you reach the eastern edge of the cliff bands. Head for this point.
http://good-times.webshots.com/photo/2363673090061435028PbZDNwThis is where your climb begins.
Follow this route up through the cliff band
http://good-times.webshots.com/photo/2160477340061435028SiofEHEnter the cliff band and walk mostly level about 50-75 feet. Then climb up to the right here....the climb up is only about 20 feet. It is class three on good rock. If you have a backpack you might with to climb without it and lift the backpack up with a short rope. We did not not but it would be safer to climb without a large bulky backpack.
http://good-times.webshots.com/photo/2456896480061435028LggLDFOnce to the top of the climb through the lower cliff band walk mostly level to the west (left) again for 50 - 100 feet or so. From there you can climb up through the upper cliff band....which climb doesn't last long before it opens up. This is also class three with good hand holds. Same rule applies to heavy backpacks, which would be difficult to climb with.
http://good-times.webshots.com/photo/2517701700061435028zzRfhuOnce through the more difficult climbing of the upper cliff band, continue to head upward through scattered rocks until you get to this point.
http://good-times.webshots.com/photo/2074340730061435028RlSiThThis is where you head diagonalB to the plateau that extends out from Discovery Pinnacle. We used an arch to head up to the large snowfield below the rock wall area, following the base of the snowfield until it connects with the ridge coming up from the left. It is to your advantage to come out on the ridge as high as possible.
http://good-times.webshots.com/photo/2479568580061435028GFKVtKOnce you reach the plateau, head toward the highest point, Discovery Pinnacle.
http://good-times.webshots.com/photo/2143974950061435028zeWgAKThat is where you drop down to the Mt. Whitney trail...on the right side (east) of Discovery Pinnacle.
