Descent options from the summit of Mount Stuart. Yellow is Ulrich's Couloir (4th class). Red is the most popular descent down Cascadian Couloir. Blue is a variation on the Cascadian Couloir (I think) that might be a bit quicker. We descended the red line following a distinct trail so I assume it is the Cascadian. However, there is conflicting information as to whether the red or the blue line is the actual Cascadian Couloir. Please correct me if I'm wrong.
