THE SANTA FE ROUTE, 
largely from the adjoining mountains of gneiss, but they include also 
some volcanic tuff and agglomerate and old lava (basalt). The beds 
are tilted at various angles, the dip being to the southwest in a con- 
siderable area west of Klinefelter and almost due west, at angles 
approaching the vertical, along the foot of the Dead Mountains, 
northeast of that place. A short distance beyond Klinefelter sid- 
ing a number of springs issue from this deposit, affording water 
which has been extensively utilized by the railway company for its 
locomotives. These springs are just west of the track. 
A few rods east of the railway, at milepost 590, a mile north of 
Klinefelter, the conglomerate stands nearly vertical and includes 
between its beds a 6-foot sheet of basalt. Ata place just east of the 
tracks it includes another sheet of basalt. 
At Klinefelter the railway is in a wide desert valley that is drained 
through Sacramento Wash, which heads far to the west. To the 
east rise the Dead Mountains,' culminating in Mount Manchester; 
to the southwest is Ibis Mountain, which ends southwest of Ibis 
siding. The up grade continues past Ibis to the summit, half a mile 
east of Goffs. The divide at this place (altitude, 2,584 feet) is in the 
wide sand plain of the desert, but there are ridges of granite not far 
to the north and south, and doubtless here this rock is at no great 
distance beneath the surface. At Goffs, however, in a well 926 feet 
deep, from which the railway company obtains water, the first rock 
reported was at a depth of 680 feet. 
A branch railway leading to Barnwell and Searchlight, two mining 
camps to the north, begins at Goffs, which is an old settlement, sup- 
ported mainly by gold, silver, and copper mines in 
Goffs. the mountains to the northeast, northwest, and

This, consist of schists, in most of which 
the foliation is well defined, dipping in 
part at a low angle to the west. The 
slopes and ridges south and southwest of 
Klinefelter show a variety of rocks. For 
the first few miles there is much breccia 
and conglomerate that include sheets and 
masses 
rhyolite and breccia, which appears 
in knobs and finally rise in prominent 
peaks near Eagle Pass, 10 miles south of 
Klinefelter. For about 2 miles the gran- 
ite and rhyolite are separated by lime- 
stone and sandstone, which are of Paleo- 
zoic age and contain at one point fossils 
that are probably Carboniferous, Six 
miles southwest of Klinefelter is the high, 
conspicuous Tabletop Mountain, consist-

of rhyolite. The high ridge next north-
