Start on the left arete of the Colossus boulder down below the main landing area. Just behind the lower left corner is a finger crack to follow up the arete to a great horizontal. From here work your way up the arete to a great hollow flake, move right into a great horizontal. Fire up to the jug atop the flake on the arete, then work your up the arete using slopers and pinches to a decent flake just right of the arete up high. Continue to work the arete to the topout point of Orion. This climb has some very cool moves up the arete to the great mantle.
3 Pads at least!!!
