THE SANTA FE ROUTE, 151 
By the judicious use of a small amount of water and fertilizer, 
date palms, cottonwoods, and various other plants have been culti- 
vated at Danby, making the place an oasis in the 
eabad Water is obtained from a well, and an addi- 
res supply is brought by a pipe Gans a spring 4 
ules to the northwest, where a tunnel has been run 
into the hillside i in such a way as to onthe the water seeping from a 
small fissure in the volcanic rocks. Clipper Mountain, with its bright- 
colored slopes and steep pinnacles of volcanic rocks, is a conspicuous 
feature north of Danby station. Five or six miles east of Danby 
are the Piute Mountains, and to the southeast rises Old Woman 
Mountain, both ranges presenting long, bare slopes and rugged peaks 
of granite. 
From Danby to Siam, a distance of 7 miles, the railway descends 
the broad desert valley on a southwesterly course. Southeast 
of milepost 640 several scattered knobs‘ of volcanic 
rock rise from the desert a short distance east of 
the tracks. These are outliers of Ship Mountain, 
a short but prominent range which continues to a 
point 7 or 8 miles southeast of Siam. A deposit of volcanic ash 
and some associated tuff in the ridge 3 miles east of Siam is about 
100 feet thick, and portions of it are snowy white and sufficiently 
pure to be serviceable as polishing powder. Material of this charac- 
ter is used in many of the cleansing powders now on the market. 
A short distance south of Siam there is considerable limestone, 
most of which has been changed to marble by the heat of intruded 
granite. This marble constitutes a high ridge 2 miles southeast of 
Siam and several outlying knobs west of the foot of the ridge at 
intervals southward for 24 miles. The marble is cut off to the north 
as well as to the south and southeast by the granite constituting the 
central portion of Ship Mountain. In the Siam mine, 2 miles south- 
east of Siam, which was worked for several years, considerable gold 
and copper ore was found along or near the contact of the marble and 
granite. In places in the altered limestone east of Siam there are 
seams and pockets of yellow and red ocher of excellent quality. 
This material is extensively used for paints. 
North of the railway beyond Siam are the Iron Mountains, a 
narrow but prominent range which is in general a southward contin- 
Danby.
