The Exploration of the Colorado River in 1869. The Exploration of the Colorado River and the High Plateaus of Utah in 1871-72. From the introduction- "More than three-quarters of a century has passed since Major John Wesley Powell's parties began their exploration of the Colorado River country, yet the records of the Powell exploration have a freshness, an immediately contemporary interest, that few records in the annals of American exploration still possess. Roads, even superhighways, have been built into the most parched of the West's deserts, and over or through its most formidable mountain barriers, but one who would know the Colorado country must still penetrate it as Powell and his men did in 1869 and 1871-72, by taking to boats or resorting to pack trains."
