DESCRIPTION OF THE AREA. 



Kimball County is located in the extreme western part of the 

 State of Nebraska. The county adjoins the State of Wyoming on 

 the west and Colorado on the south. It is bounded on the north 

 by Banner County and on the east by Cheyenne County. Kimball, 

 the county seat, is 451 miles by rail west of Omaha. The county is 

 nearly square and has an area of 958 square miles, or 613,120 acres. 



Kimball County lies in the physio- 

 graphic province known as the Great 

 Plains. It is in the western part of this 

 province, in the division known as the 

 High Plains. 



Topographically the county consists of 

 a moderately rolling plain, dissected by 

 the valley of Lodgepole Creek, from 1 to 

 2 miles wide and about 200 feet deep, 

 extending across the center of the county 

 in an east- west direction. It is sharply 



defined, with broad areas of undulating table-land on each side. The 

 valley is characterized by steep upper slopes, or bluffs, with gentle, 

 extended slopes at the base which merge into a nearly level valley 

 terrace, the profile having roughly the shape of the letter U. The 

 creek winding through the valley has a narrow recent flood plain 

 lying about 2 to 4 feet above the stream, Avhich is subject to overflow 

 at infrequent intervals. A well-defined alluvial terrace of smooth, 

 nearly level, or gently sloping topography lies at elevations of 20 

 to 40 feet above the creek, and a high bench, 60 to 80 feet above, 

 occurs in places, although its outline has been obscured and its 

 original covering of alluvial deposits largely removed by erosion. 



The surface of the county is a constructional plain, built up by the 

 deposition of rock debris washed from the Rocky Mountain region 

 to the west in late Tertiary time, the original surface configuration 

 not having been greatly modified by stream erosion. The two areas 

 of upland, popularly referred to as the " table-land " or the " divides," 

 have much the same character of topography. There are numerous 

 shallow drainage ways, so that the land for the most part is slightly 

 rolling, although a considerable part is nearly level. The drainage 

 ways, or " draws," in their upper courses are simply broad, shallow
