Carp, as I have only been there once, not 100% on anything, but approach should be no problem from Irene after effects because the terrain on the approach is mostly an old logging clear cut, is mostly young saplings and blackberry bushes, just stick with the trail, heading to left side of cliff(trail will be several hundred yards outside base of cliff, not right at the base), until end when it loops back toward cliff, is a minor wooded 5 minute bushwack to base of Oct Sundae from trail(should cross a small stream not far from base of cliff) once you are at left side of cliff, beaten down circle at base of Oct Sundae, took us a couple minutes thru the bushwack to find, but no biggie
Drying wise, my guess is since cliff is mostly slabs, the open slabs should dry out quick and be climbable a day after rain, but all areas at the base of cliff (1st pitches) have a lot of tree cover and those places probably stay wet longer as well as the many "gardens" and tree patches thruout the cliff will remain wet longer, would guess you could still put something together if you can deal with some wet spots
was planning an entire weekend up there starting today but with rain today and saturday, not worth the 2 1/2 drive for me and the boys to prob be let down with pure wetness, Sunday might be doable, We cancelled up there until next weekend, cant wait to jump on other climbs, my 5.10 leader buddy wants to lead that 5.10C arete, I cant wait to follow!, plenty of 5.7s and 8s for my modest ability, and my bad knee, great cliff
