The U.S. Issue - The Mighty Colorado at a Glide - NYTimes.com: "THERE we sat, five paddlers in three canoes on the Colorado River in northern Arizona, simply observing. The setting sun washed the 1,500-foot canyon walls in hues of coral; cotton-puff clouds dotted the pink-tinged sky. The still surface of the river so perfectly mirrored the cliffs and sky that it was hard, at a glance, to know where the river ended and the cliffs began. Except for a few ducks dallying on the shoreline, we were alone."
