Thanks for posting this page, great photos. Need to update the lat/lon though. Coordinates should be around Lat 45.1484, Lon -114.6105.
My brother and I did a 4 day trip into the crags a few summers ago, wish we could have stayed longer. Got pretty close to the summit of this peak while crossing the ridge on our way from Terrace Lakes to Ship Island Lake. We were at the saddle east of Peak 9743. I regret not taking the short traverse over to Sheepeater Mountain. Did get one good photo of the steep west face of the peak. Here's a link.
