466 
and 2,267 meters. The people in the neighborhood insist upon calling 
it 8,000 feet. Next.in height comes Crooks Tower, the highest point 
on the Limestone Plateau on the west side, with the altitude of 7,325 
feet, or 2,232 meters. The altitude of Terrys Peak, one of the igneous 
cones in the Northern Hills, is 7,215 feet, or 2,200 meters, and Custers 
Peak, another igneous cone in that neighborhood, is slightly lower. 
The general height of the Black Hills is between 1,500 and 2,000 
mneters. . 
PRECIPITATION AND TEMPERATURE. 
The precipitation of the Black Hills is very large compared with 
that of the surrounding country. There are no records of the annual 
rainfall in that part in which, judging from the nature of the flora and 
the luxuriant growth of the vegetation, the precipitation must be the 
largest, viz, in the Harney Mountain Range. In fact, there are no 
records from any place in the higher part of the Black Hills. 
Table showing the average monthly and annual precipitation at the Weather Bureau stations 
in the Black Hills, compared with that of four stations on the plains and three stations 
within the Rocky Mountain region.
