|General Route Info||"As the name implies, you should be near the top of the couloir when day breaks, as it is a natural funnel for rockfall." "Approach from Pole Creek Spring. Climb the couloir (maximum angle about 45 degrees). Near the top there are two choices. Go around the right side of the headwall formed by Glisan Pinnacle, or climb the headwall directly." "From the top of Glisan Pinnacle either climb the NE shoulder of Prouty Pinnacle or descend and climb the regular westside route." -Jeff Thomas, in Oregon High|
