March 10 2020 Columbus Canyon is only a few minutes from my house and since we had Monday off, it sounded like a good target for the day. Dan Harper, Kimberly, and I met at the Lunch Loop Trailhead before leaving one car at Devils Kitchen Trailhead and one near the head of the canyon. We then walked around to the head of the canyon and down climbed in. There were some interesting downclimbs and two overhanging rappels in the sandstone section of the canyon. The second rappel was next to a big frozen waterfall. We then scrambled down canyon and found several old and smashed up cars that must have been driven or pushed off the rim, some 500 feet above. The next section of the canyon was pretty easy until we got to the granite. Then there was some really interesting downclimbing in the granite before reaching out last rappel, which was over a frozen waterfall. This was the last major obstacle, but there were still a few downclimbs before we reached the national monument boundary. We then hiked along the boundary and back to Devils Kitchen. Columbus Canyon lacked a slot section, but it was an interesting technical canyon and passes through many different rock layers.
