lateral moraine of Twin Lakes in the foreground. 
On the east (right) the side of the valley for some distance is very 
hummocky, and on first sight it seems to be a moraine, but closer 
study shows that the glaciers which once came down the gulches on

this side of the main valley did not extend to the area that is within 
sight of the railroad, and the hummocks are therefore not the result

At milepost 267 Mount Sheridan (13,700 feet) is the most conspicu-

the peaks of this range are not so rugged nor so high as those of the 
Sawatch Range, on the west. 
After passing milepost 268 the traveler may see on the east (right), 
by looking up the gulch past the white wooden schoolhouse, the first 
indication of the presence of the great mining camp of Leadville—

_‘At milepost 269 a good view can be obtained of the Mosquito Range, 
known also as the Park Range, on the east. The view from 
this point is represented in the accompanying sketch (fig. 25),
