WHITE EIVER. 



White River heads in high plateaus, which reach the timber-line. Its 

 general course is westward, varied by occasional curves toward the 

 north and south. From head to mouth it traverses plateaus, mainly 

 inclined at low angles. Throughout it flows in a valley, through most 

 of its course narrow, and limited by caiion-walls. The arable belt is 

 narrow, nowhere exceeding a mile in width, excepting in Simpson's 

 Park, where the White River agency is located. Here the valley spreads 

 out, making an irrigable patch four or five miles in width by about the 

 same length. 



Of the branches of White River, the only one having any arable land 

 in its caiion is that known as Piceance Creek, which has a narrow belt 

 along it for twenty miles above its mouth. 



The whole amount of arable land on the White River drainage, an 

 area of 3,600 square miles, is 174 square miles, an area by no means 

 sufficient to use up all the water brought by the stream.
