Canyons of the Colorado

The exploration was not made for adventure, but purely for scientific purposes, geographic and geologic, and I had no intention of writing an account of it, but only of recording the scientific results. Immediately on my return I was interviewed a number of times, and these interviews were published in the daily press; and here I supposed all interest in the exploration ended. But in 1874 the editors of Scribner's Monthly requested me to publish a popular account of the Colorado exploration in that journal.
