Only had one day to fit this one in before the winter. Started from Rock Creek TH, up Boulder Cr. to Upper Boulder Lk, Secret Lake and up to Z and Z', then back the way I came. Long, rewarding, 13 hr day, solo in deep wilderness.
Traversed to Z via X and Y. From X the ridge looks very intimidating, early on dropping left was necessary for 2 or 3 large steps on the ridge. Then you can stay on the crest pretty much all the way to Y and on towards Z before 2 towers just before the Z saddle had me dropping right. Z has great summit views!
Got a double dose of the Pitkin Lake trail after doing the Partner traverse the day before. Followed it to 11020' and went over Useable Pass. Had a party on the summit of Z for Sarah's 500th ranked 13er in CO. Kudos, Sarah! Continued on to Y and X for a nice ridge run. The ridge is easier than it looks with just a few towers to drop below.
