Our alarm went off at 5:15 and we drove into the park to watch the sunrise from Mather Point. We chose a spot at the edge of the rim and sat in the gravel. We layered on all the long sleeves we’d packed, but were still chilly in the pre-dawn darkness. We saw a glimmer on the ridgeline below and then a little cloud of dust. We looked through the binoculars and saw a small building and a group of mules carrying visitors to the canyon floor. We watched the cloud of dust travel along the ridge and descend below the ridgeline, all before the sun peeked over the horizon. Unbeknownst to us, we would find ourselves traveling by foot on that same trail just a few hours later.
