Katahdin's Armadillo Butress has to be the Northeasts most stunning alpine line. 2000' off the pond and overlooking the huge s. basin. one couldn't get a better view. The climb is detailed in Waterman's Yankee rock and ice (pg's 164-169). Other than that , Stewart Guay the alpine ranger at Chimney Pond ( At Roaring Brook in the summer.) could give you specific beta once your thier. Also, try Jon Tierney at the University of Maine at Orano ( Maine Bound )& Acadia mnt. guides in Bar Harbor. ( both have web sites, just do a search on Yahoo.)
Long approach....and unless you've booked a site at Chimney pond your hiking in / out to at least roaring brook's parking lot ( 6 miles total.) ....mabey longer. Plus you'll have to deal with the park authorities unending BS . All together though , well worth it...if you don't mind BIG BROTHER watching your every move !!!
