This guy Jim Beyer rope soloed a bunch of routes in this Mother Buttress area in 2007...might be some of his? With him one day I repeated about four of his routes that seemed around 5.11. He wanted to relead them with a belayer. He pointed out a few more he had done. I know he was also active with single pitch climbs further down the canyon on a previously unclimbed crag. Do not know if he ever wrote up any of these climbs?
