Its a neat range, lots to climb. Rock quality leaves much to be desired. For most folks, anything in the northern pickets will be a 2 day approach, 2 day deproach using any of the ways in. Allow 4 days to get in and out of high camp. There's not really any bushwhacking to get into either side of the range with the standard approaches. If I were doing something in the southern pickets, I'd search trip reports here, then supplement with Beckey guide and/or Nelson select guides.
