Ken, I always thought impressive is your solo of the West Rib of Denali and Mt. Assiniboine.
My finest solo, Ken, on ice/snow was the Italian Climb (Scottish grade 4) (links to Tower Ridge-before the gap) on Ben Nevis, Scotland. I spent a winter climbing in Glen Coe and on the Ben. Soloed many 3's and 4's. Rented Allan Wedgewood's (on FA of Sam's Swan Song, Reppy's, and other Cannon climbs) Cottage along Loche Levin outside Glen Coe for 5 quid a week ....many an evening knocking down Ales with local luminaries-most memorable night with Joe Brown holding court!
Also, quite a few ice climbs in the Adirindacks up to grade 4.
Rock: Solo cruising both up and down, bare foot, all the facets of Chapel Pond Slabs. Quadraphenia, Hurricane Crag, ADKs.
Lakeview, Con Prize, wiesners, funhouse to upper refuse.
