 western and more precipitous side of 

 Sugar Loaf hill. Into White-tail creek 

 from the west empty a series of almost 

 parallel gulches heading up on the 

 eastern slope of Terry Peak and Green 

 Mountain. The most important of 

 these are Fantail gulch, which con-

 gulch, which forms a deep gorge just 

 south of Bald Mountain, the two unit-

Still to the north of Bald Mountain 

 are two important streams. False Bot- 

 tom and Deadwood creek. Both head 

 up near the town of Portland, the first

 the plains of Centennial Park, but the 

 second, with its many tributaries, to 

 flow through a deep and often rugged 

 ravine so as to unite with Whitewood 

 creek at the city of Deadwood. 



Probably the most notable topo- 

 graphic feature of the entire district is 

 the predominant position of Terry 

 Peak, from which the surrounding 

 country gradually declines in every

The surrounding country rises gently 

 from the more or less level ground to 

 the south and increases its rate of ele- 

 vation slightly, until, with a long, shal- 

 low sweeping curve, it culminates in
