D. and I could not find the slot canyons that M. explained to us back at the ranger station. We were supposed to come to a fork after the canyon narrowed and crawl over the boulders to the right. What is a fork? What is a canyon? What is a narrowing? What is a boulder? Instead we climbed up something I could not imagine climbing up and ate our sandwiches in the hot hot sun. What goes up must come down, which was cold comfort from that height and angle.
