Exploring Nests of Golden Eagles 
By CHARLES DARWIN TEST 
DURING EIGHTEEN YEARS I spent as a resident of Golden, Colorado, from 
1900 to 1918, while a member of the faculty of the Colorado School of 
Mines, much pleasure was derived from studying the birds of that locality. 
Because of its situation, just at the base of the foot-hills, fifteen miles 
west of Denver, Golden has a varied bird population, for one finds not 
cnly the true mountain species, but also many which are really birds of 
the plains. The altitude of Golden is about 5,600 feet, a few hundred feet 
higher than Denver. On the east side of the town is an extensive, basalt- 
capped mountain which has been cut into two parts, called North Table 
Mountain and South Table Mountain, by the stream known as Clear Creek, 
which flows from the mountains just to the west. The Table Mountains 
Castle Rock, near Golden, Colorado 
have an altitude of a little over 6,000 feet, while the elevations farther 
west rise to 7,500 to 8,000 feet within a few miles from the town. From 
these mountains and those beyond issues Clear Creek, via the famous and 
seenic Clear Creek Canyon, the eastern end of which is only about a mile 
from Golden. 
The Table Mountains are interesting and more or less well known 
because of some of the minerals found there, especially certain of the 
Zeolites, specimens of which are to be found in many mineral collections
