AN IMPORTANT REPORT ISSUED.
Continued from page IL


the location of every coal mine anl
prospect in the district.
The opening paragraphs in she de
scription of the general nature and
location of the Book Cliffs gre as
follows:
The Book Cliffs occupy belt from
to 10 miles wide and rise above the
adjacent Iowland from 1000 To 6,00O
feet. In places the rise is abrupt in
one or two sharp precipiccs; else
where il is accomplished by a series
of cliffs and intervening benches. The
rocks comprising the escarpment are
alternating beds of sandstone and
shale dipping slightly northward, and
the strata present the appearance of
the leaves of a book lying fiat, hence
the name.
In the area here discussed the cliffs
extend in an S-shaped belt from Pali-
sade TO Sunnyside. AT the east they
are much dissected by Roam creek.
and a subordinate escarpment known
as the Little Book Cliffs extends
northward from the mouth of Hog
back canon. The top of the Little
Book Cliffs marks the crest of a ridge
whose northeastern flank constitutes
a dip slope. and the area between
Little Book Cliffs and Roam creek is
a gentle northeastward-s -sloping mono
cline dissected by southeastward-
flowing streams
Climta and culture, descriptive
geology. general statement as TO the

and every mine in the district, char

and many other interesting and i'm
portant phases of the great coal dis
trict are treated in this valuable
report,
The opening paragraph of the gen
eral statement on coal is as follows:
Coal of commercial Importance oc-
ours in the lower part of the Mesa
verde formation at various horizons
from 30 to 700 feet above its base.
In some localities several beds are
present, while in others only one or
two have been found, but no single
bed has been traced continuously for
more than a few miles. So little
prospecting has been done that an
unqualified statement can not be
made. but so far as known one or
more workable beds are present
throughout the field here considered.
The thickness of the coal ranges from
maximum of 81 feet. down to mere
films of carbonaceous matter, The
beds outcrop in the face of the Book
Cliffs commonly 100 feet or more
above their bases, and at distances
from the Denver and Rio Grande
railroad which vary from close proX
unity to a maximum of about .
miles. The dip is at a low angle
northward and the coal underlies an
immense area north ofthe cliffs. The
coal of good quality and compares
favOrably with that from the Rocky
mountain fields. IL is but little pros
pected, however, and there are only
four small mines with railroad con-
nections between Grand river and
Sunnyside.
The descriptions of the various
mines. their tonnage, etc, form a
most important portion of the report.
The report is not only of great
value to mining men but it gives a
clear insight to all residents of this
section of the marvellous mineral
wealth of the Grand Junction and
Eastern Utah districts.
Some time ago The Sentinel con-
tanned the first announcement of the
preparation of this report and gave
brief prospectus of its contents but
the completed report has just been
issued and copies were received here
Saturday by numerous local organ
izations and persons.
