I peered over the backside of the couloir and was stunned. From my earlier visit to Whorl Mountain I knew that despite the severity of Matterhorn's north face, its south slope was gentle class 2 talus. The guidebook even mentioned that the East Couloir was the easiest way to gain the summit, so I'd assumed that the West Couloir would be similar. Instead I was presented with a shear granite face.
This is far and away both the largest and the most experienced group of people I've ever hiked with. I don't imagine I will have to worry about the group slowing me down much during this trip!
