Sir: In the February 3rd~num
ber of your journal | gave an ac-
count Of the beds of photographic
stone found on the east slope OF
the Verde Range, in Yavapis
county, south OF Squaw Peak,
Shortly after tins discovery a
similar bed was found on the west
slope OF the same range and some
6 or s miles Southwest of the first
mentioned. This discovery was
ct the head of Sys more creek,
elevation about 5,4OO tt. above tide
and distant from Prescott about
45 miles by present wagon road.
This stone has been tested by a
prominent firm of photographers 10
New York and pronounced equal to
the second quality Bavarian stone
which is worth in New York 5000
per ton.
In July I made an examination
OF this deposit and found that the
beds had been opened at six differ
ent points. Three quarries are on
the sonsh side OF the gulch but
few feet above the water line, while
the highest the most easterly one
--on the north side is 200 #. above
gulch. There is plenty of evidence
to show that there has been a verti-
cal displacement IN the formation
along the line of the gulch of about
300 it,, therefore the beds on the
rwo sides are one and the same.
The dip of the strata is very slight
ly to tbs northeast into the mount
ain.
Taking both sides Of the gulch
you have an outcrop of something
over two miles in length. One of
the openings shows total thick
ness of about Is #. of photographic
stone, the other openings are not
sufficiently large to show the thick
ness at the other points.
GeoIogically the formation is the
same as that Mt Sqnaw Peak, viz,
Upper Carboniferous. The gulch
being 700 to 500 IT. deep, and the
sides very steep. an excellent sec
ton of the rocks can be seen.
At the top there is layer of lava
about 100 #. in depth and the diff
ference in elevation OF the laya bed !
on the two sides OF the gulch shows
that the disturbance or fracture
and possibly the elevation Of the |
ranges took place subse
quent to the lava flow; that Is, post
frIassic.
About l25 It. below The beds Ii

The most interesting fea-
,ure, however, OF the section OF
rocks is in the 100 IT. OF measures
above the photographic stone.
Within this depth are a number of
beds Of rock, similar in character or

The beds are also more solid.
