boundary is about 2 miles south of the tracks near Savoya siding. 
To the southeast of this siding is a high volcanic range in Mexico, a 
southern extension of the Carrizalillo Hills. Far to the southwest 
is the Sierra Boca Grande, also in Mexico. 
Near Victorio siding (named from the Apache chief referred to on 
p. 147), which is in the middle of the valley, the rounded slopes of the 
Cedar Grove Mountains extend along the north side 
of the valley, and the more rugged outlines of the Sierra 
Rica rise prominently to the southwest.” About 1% 
miles west of Continental siding there is a sign read- 
ing ‘‘Continental Divide,’’ but this is a mistake, as the 
basin of Hachita Creek, to the west, empties into the Rio Casas Grandes 
in Mexico, which, like other streams east to Arena, drains into Lake 
Guzman. This is, however, the highest point on the railroad west of 
the Rio Grande, being 4,745 feet above sea level. The Continental 
Divide is crossed 20 miles or so farther west. (See p. 168.) From 
this sign west there is a down grade to Hachita (ah-chee’tah). North 
of the track on this grade is a long, narrow ridge capped by lava 
(basalt), which probably originally flowed down a valley and pro- 
tected the area which it covered, while the adjoining surface was being 
eroded to a lower level. This is an interesting example of an old 
stream bed at a higher level than the new ones. 
The Apache Hills, south of the railroad, consist mainly of intrusive 
quartz porphyry overlain by Tertiary volcanic rocks to the north and 
in contact with limestones of Comanche and probably Magdalena age 
to the south. There are several mines and prospects in the range; 
the largest is the Apache mine, which has produced considerable 
silver ore. 
Hachita, in the broad Hachita Valley, i is a small settlement, railroad 
junction, and headquarters for mining interests in the adjoining 
Ae © mountains. Several of the mines in the general 
(sit. region have had prosperity, and some are believed to 
os hold considerable promise. The most productive 
m0 ae. 1,305 mines are in the Sylvanite district, in the Little 
Hatchet Mountains, about 10 miles southwest of 
Hachita. (See sheet 20.)
