If only it could go on forever. Literally the only flaw in this perfect line is its diminutive height. An ideal first lead or solo, the left-facing flake is followed via perfect jugs to a flat topout. Gritstone doesn't get any better, and neither does VDiff.
Location
Just left of the towering mass of Mississippi Buttress, right of the dramatically worse-looking Hell Crack.
Protection
A little hand-sized gear. Vastly better to solo it.
