The Dragon of Waters was vanquished.

Below this point Powell was guided by a manuscript journal which Jacob Hamblin and two other Mormons, Miller and Crosby, had kept on a boat journey a few years earlier from the Grand Wash to Callville.

Ives and others having been up to Callville, the exploration of the Colorado was now complete.

There was no part of it unknown; and Powell's feat in descending through the long series of difficult canyons stands unrivalled in the annals of exploration on this continent.
