PHYSIOGRAPHY AND DRAINAGE 



The area covered by this report lies in the transitional region 

 between the Shoshone Mountains on the west and south and the Big- 

 horn Basin on the east. Its average elevation is about 6400 feet, or 

 abotit 1400 feet higher than the average for the Bighorn Basin. The 

 streams from the near-by mountains occupy comparatively narrow, 

 flat bottomed valleys, flanked by well developed stream terraces. Cut 

 terraces, covered with a thin veneer of fluviatile gravels, are among 

 the most striking topographic features of the region, forming as they 

 do long, flat topped ridges usually paralleling the rivers. Along Wood 

 River there are two well developed terraces, the higher 600 feet and 

 the lower 200 feet above the present stream valley. These slope gently 

 to the north at about 90 feet to the mile, which is very nearly the 

 same as the fall of the river, and are shown in plate 37. 



The principal drainage of the region shown on the map is through
