its tributaries. The Little Medicine has in this region two principal 

 branches. Sheep creek, its eastern branch, rises among the foot-hills 

 of the Laramie mountains, flows in a general south w^est direction, and 

 joins the river at a point almost directly east of the southern border 

 of the Freeze-out Hills. Muddy creek, the western tributary of the 

 Bow, has its origin north and west of the hills, flows for some dis- 

 tance nearly straight east, turns first southeast, then south, and enters 

 the parent stream a few miles below the mouth of Sheep creek. Thus 

 Muddy creek and its branches receive the northern and eastern drain- 

 age of the hills. 



A few miles below the mouth of Muddy creek the Little Medicine 

 Bow river, which, north of that point, flows for some distance almost 

 directly south, turns sharply toward the west, and, flowing not far 

 south of the hills, receives their southern drainage through its north- 

 ern branches. On the west the drainage is effected through Trouble- 

 some creek, which is also a northern branch of the Bow. 







Topography. The topographic features of the region are bold and 

 rugged. The hills have been carved out of a great anticline by 

 streams which in many instances flow almost parallel with the dip 

 and across the strike of the strata. In general outline the group forms 

 a great semicircle, with an abrupt central ascent and a gradually sloping 

 circumferential descent. The maximum height of the hills is between 

 500 and 600 feet. The dip of the strata which compose them is about 

 thirteen deg. although at first sight it appears much greater than that. 

 The individual hills have an abrupt central or western approach and 

 a far less precipitous outer approach. The occurrence of alternating
