The drainage exit is through the Uintas, as noted, by means of the canyons heading at Flaming Gorge.

There are here opportunities for extensive farming by irrigation.

The only other chance for agriculture on the river, except Wonsits Valley, Brown's Park, and a few minor places, is below Black Canyon, in the stretches I have called the alluvial and the canyon-valley divisions.

In the latter short canyons separate extensive valleys with wide alluvial bottoms capable of high cultivation, though often subject to overflow.

Almost anything will grow there.
