The fourth morning of a twenty-one day raft trip in March and April, through all 270 miles of the greatest of canyons in the Earth found me here, having climbed about 450 vertical feet from our campsite, visible below. Note the six rafts, mostly over 16 feet long. The bushes beyond are tamarisk trees about 20 feet high. Up to three thousand two hundred vertical feet of rock is visible, and the center of the hazy canyon wall in the distance is no less than four miles from where I stood.
