Coal Deposits Found
The anthracite deposits of Sonora
are found between the Sierra de San
Marcial TO the west, the Sierra de
Baeatete 10 the south and the Sierra
de Onavas on the east, with the Mesa
de Advino as the northern limit
Probably before the geological dis
tuTbances that occasioned the forma-
ton of the San Marcial and Baca-
tete mountains. the coal deposits
were extended toward the west, but
the continuous currents of water dur
ing thousands of years. that has
flowed down the slopes from the 81
ezra Madres TO the gulf have grounn
up and carried to the sea, both coal
and the enclosing slate, leaving 20
the west and south the granite and
porphyries, of which the mountains
OF this region are formed. II is Ger
tain that both the groups of San
Marcial and Bacatete. 0n being ele
waited. broke the coal strata, and
formed a dam 20 the currents that
flowed from the crest Of the Sierra
Madres, and so formed an immense
lake over what today are the coal
deposits This lake which received
the currents of the sieTras, also re-
ceived the sand. rocks. etc, that they
carried and formed thick cap over
the coal, and though il was buried
hundreds OF feet below the surface, il
was saved from the destruction SUI
fered ~ that portion not 50 favored.
II is presumabie that in time the wa
tiers opened pass at the Punta de
Agra and formed the stream now
known as the Rio de Matape. The
same thing should have happened
where the canon OF the Yaqui cuts the
mountains to reach the sea. The seq
imentary strata that formed the bot
tom of the lake is co-eNtensige with
the carbonaceous formation, as has
been proven by perforations made in
exploring the coal, which only ap
pears on the slopes OF the hills,
where volcanic 90 activity has brok-
en- and elevated the beds, bringing
to the surface that which otherwise
would have remained buried. In all
| OF this basin of more than 20 square
I leagues. there is found nothing b.;
anthracite, which has been formea
from the original bituminous coal by
