you got it. nice detective work! and yes i suppose that wasn't fair to include a side junket. i just figured that since you are mr. adventure, you would've climbed it already, and would know the banner-ritter saddle on sight. but given your pace on the SHR, you probably didn't have any time for side trips!
i identified a few possible easy climbs before we headed out on the SHR (e.g. split mountain, columbine peak, black giant, banner peak, and vogelsang). but given how snowy and suncupped and slow the first seven days were to get to piute pass, we didn't dare stop to climb split. and then, as we talked about, columbine looked kinda class 3ish and we were still hustling to resupply. when we headed past black giant, we had to climb muir pass, alpine col, and down piute in one long day of snow, so we didn't give it a second thought.
we got to lake catherine around 3 or 4 in the afternoon, and convinced ourselves we should bag banner vs. head down the unknown terrain towards bench canyon. so up the easy snow slope to the saddle, and then it's just a LONG slow climb up talus. i'm not much for going uphill, so it seemed like a long while. and then kinda of suddenly, you are at the top. the view is INCREDIBLE. we hung out for a good amount of time, took lots of pictures, and then descended to the saddle. just before we reached it, a chunk of talus moved and i fell flat on my side on some rocks and must have cracked a couple ribs, which hurt for weeks after. a bit of glissading and walking down to camp. highly recommended!
