SURVEY OF THE COLORADO OF THE WEST. 15 
ture-lands and grass-lands to the south, on the slopes of the Uintah 
Mountains, would be of great value to settlers. 
Brown’s Park is a valley twenty miles long and from six to ten miles 
wide; it is an expansion or widening of the canon of the Green where 
it has a westerly course. Eight or ten small but beautiful streams come 
down from the mountains on either side, and can be easily controlled 
and used for purposes of irrigation. 
Forests of cotton- wood are found along the flood-plain of the river; 
the hills further back are covered with cedars, and the mountains on 
either side carry great forests, and a few miles to the north are exten- 
sive coal deposits. This valley is a few hundred feet lower than the last 
mentioned, and hence much warmer. 
On the south side of the Uintah Mountains we find a broad, rich valley. 
A large body of land can be cultivated here by the use of the waters of 
the Green, but will require a large outlay of capital. It has many natu- 
• ral meadows, and a warmer climate than either of the last-mentioned 
valleys, being but little more than 5,000 feet above the level of the sea. 
The valley of the Uintah and its branches is one of the finest known 
to me in all the southwestern portion of the United States. The Uintah 
has more than a score of important tributaries, all running near the sur- 
face, easily controlled, and capable of furnishing sufficient water to irrigate 
more than 150,000 acres of the adjacent lands, which are well situated 
for that purpose. On either side there are grass lands of value, and in 
the mountains to the northwest, and the Ta-va-puts plateau to the 
south, there are pine-forests practically inexhaustible. Along the lower 
valley of White Eiver there are extensive bodies of lands which can be 
redeemed by taking out the waters of that river, but it will be attended 
with much expense. 
South of Gunnison Plateau, along Green Eiver, is Gunnison Valley; 
here a narrow belt of laud can be cultivated by taking out the waters of 
Green Eiver, but this can only be done by the expenditure of large cap- 
ital. Below this point all of the tributaries of the Colorado Eiver within 
the country under consideration, run in their lower courses through 
canons affording practically no area for cultivation, but along the mid- 
dle courses of these streams there are many valleys and parks of limited 
area which will eventually be settled. Already pioneers have penetrated 
into some of them, as the Eio Virgen, Eanab, Paria, and Escalante. 
HYDROGRAPHY. 
The hydrography of the country is intimately associated with the study 
of the valleys, for under favorable hydrographic conditions only can they 
be cultivated. The amount of water carried by the Colorado and its 
tributaries has been carefully estimated. The springs also have been 
located, and mention will hereafter be made of them in the geological 
section of this report.
