and crater formations, canons, petrified trees, and 
sulfur springs. Its geysers are the finest in the 
world. It has beautiful lakes and waterfalls. A great 
portion is covered with forests, in which wild animals 
of many kinds are protected. The bison roams about 
the park without molestation, since shooting is not 
permitted. 
Farther to the east, on the line between Wyoming 
and Montana, the Bighorn Reservation is located in a 
range of mountains of that name; and still farther 
east (the new Wichita Reserve in Oklahoma is now 
farthest east), in South Dakota, bordering on the line 
between that State and Wyoming, is the Black Hills 
Reservation. These mountains are surrounded on all 
sides by prairies. The conservation of the timber is, 
therefore, a matter of great importance. One of the 
most interesting natural wonders of this district is 
the Wind Cave. The cave is of great extent, in fact, 
contains miles of galleries and chambers, and a full 
complement of stalactitic, stalagmitic, and other for- 
mations of notable beauty. Much wood is used in 
the extensive mines of this district. 
North of the Yellowstone Park, in Montana, there 
is a little reservation on the northern end of the Gal- 
latin Range. West of it flows the Gallatin River 
through the fertile Gallatin Valley. It is called the 
Gallatin Reservation.
