stone as well as in the limestone itself. The ore is said to carry 
high silver values, a carload shipment in January, 1904, ha vino- 
netted $4,300. At that time the shaft was 150 feet deep. The resem- 
blance of this deposit to some of those at Montezuma may be noted. 
The surrounding hills are bare of timber, and water is scarce. Tono- 
pah and Goldfield are the supply points of these prospects. 
The hills near General Thomas Cam]) have already been located. 
An abandoned tunnel 150 feet long has been driven into the diorite 
mass 1 mile northwest of the General Thomas. The tunnel was not 
visited, but ore collected by Messrs. Chapman and Spaulding con- 
sists of galena, azurite, malachite, and limonite, which appear to fill 
cavities in the diorite. In the older alluvium the writer found 
limonite float heavily stained by malachite. This doubtless comes 
from the hills to the north or south of the road. 
NORTHEASTERN EXTENSION OF THE SILVER PEAK RANGE. 
TOPOGRAPHY AND GEOGPAPHY. 
The mountains north of Lida and south of the valley in which the 
Klondike Well is situated form the northeast tip of the crescentic 
Silver Peak Range, which lies mainly to the Avest of the area sur- 
veyed. These mountains are cut off from the Lone Mountain foot- 
hills by the detritus-covered pass 7 miles northwest of Montezuma : 
they are separated from Mount Jackson by a similar gap, and a basalt 
mesa bridges the interval between them and the Goldfield hills. 
There are three main ridges, which course N. 30° E., parallel to the 
predominant strike of the Cambrian rocks. The crest lines average 
7,500 feet in height, although Montezuma Peak reaches 8,42G feet. 
The ridges are, for the most part, rather smooth, although where the 
strike of the Cambrian rocks crosses them rugged squared hills and 
pinnacles are common. The hills formed of the Siebert lake beds are 
conical peaks and gentle domes with broad valleys between. The 
north-south valley southwest of Montezuma Peak follows approxi- 
mately the crushed zone along a fault of considerable displacement, 
ida Valley is an interesting example of stream capture. The traveler 
oing up the valley from the flat north of Slate Ridge first encoun- 
ers a narrow canyon. One-eighth of a mile east of Lida the gulch 
udclenly opens into a gently sloping valley 1 mile wide. The youth 
f the canyon and the maturity of the valley suggest stream capture, 
nd Spurr, who followed the road Avestwarcl, believes that the upper 
broader portion originally drained westward to Fish Lake Valley. 
The mountains are covered with pinon and juniper above an alti- 
tude which varies from 0,500 feet at Lida to 6,800 feet on the east side 
of Montezuma Peak. A little grass grows on the upper alluvial 
Slopes and the inter-ridge valleys. An abandoned shaft at Monte-
