Climbed Columbia from Harvard and got a little of route but made the summit none the less. It was a beautiful day and luckily not a typical thunderstorm afternoon. We were on the summit around 4pm and didn't get rained on at all luckily. Descended the west slopes and was able to find some nice scree in sections to ski down which made for a fairly quick descent. However the descent was difficult in areas and I wouldn't want to climb up it.
I climbed Columbia by accident. I was trying to climb Harvard. When I left the Colorado Trail, the book said to go due west along the trail. I took out my compass and went due west. "I didn't see no stinking trail". I figured I'd go up hill instead of down and ended up high on Columbia's east ridge. I couldn't negotiate the steep snow so I went down some and traversed until I could find a way to the ridge. I followed the ridge to the summit and there I saw the first human of the day. Signed the register and proceeded to go down the north face. It was a rather easy off trail descent. When I found the trail I followed it to the Colorado Trail and back to the Wilderness boundary where the trailhead is located. I was only 10 feet off the trail. Had I gone down hill instead of up hill I would have found the trail immediately, and climbed Harvard.
Rather steep if you are climbing Columbia by itself, stick to the trail on the descent.
