Township 7 South, Eange 18 East. 



Topography. — The western half of the township consists of steep, rocky spurs 

 forming the divide between Red Lodge and West Rocky Fork creeks, and between 

 Red Lodge and East Rosebud drainage. Their eastern terminations lie in the 

 central portion of the tract where they break with sharp descents to a rolling 

 foothill region, which fills the remainder of the areas of the township with low, 

 long ridges and a multitude of shallow ravines and gullies. The general elevation 

 of the foothill region is about 5,600 feet, while the ridges in the western areas reach 

 altitudes of 9,000 feet. 



Mining. — No mineral is mined. Petroleum is thought to occur in the north- 

 west quarter of the township, where borings have been made intermittently for 

 several years, but without definite results. 



Soil. — Gravelly loam. The entire foothill region is covered with a deep 

 blanket of extremely heavy bowlder drift, partly overlain with a thin top-dressing 

 of loamy matter. 



Agricultural adaptability. — The western areas contain no tillable land. Tracts 

 in the eastern portion, in the aggregate 800 or 1,000 acres, are susceptible of 

 cultivation. 



Grazing capacity. — The foothill region, where not wooded, has a grass cover, 

 and has long been utilized as cattle and sheep ranges. Where not fenced it has 

 been badly overgrazed.
