This line of fault can be distinctly
traced all along from the divide dowu

thence towards Deer Creek, a dis,
lance OF over seven miles. crossing
two mountain ranges. The country
on either side of this fault is traverssd
by numerous fs3ure and strata veins.
which are in turn Interrupted and
broken through by several extensive
porpbSry dykes.
A grea! number of these deposits
have been opened to q more or less
extent. but IN Tot one case beyond q
depth OF 400 to 500 feet although, in
strikes soma mines have drifted for
saore than 1000 feet on the vein.
The reason for the fact that those de-
pests have not been opened beyond
certain depth is to be found in the
extensive dislocation which have
found place here. and which are Gu
h-eiy toseigz 10 mo OF the miners
ana mine owners OF this district.
There are two main lines of dis.
tsrbsncs in this district, one break
running northwest and southeast,
carrying the western portion of the
lodes downward, and another break
running north and south diagonally
to the fret break, throwing the dis
located parts further downward.
1t Is very suggestive to connect the
dlsiocstiOns of American Fork with
the disturbances which found place
during the time of the second up
hesval, which are 80 plainly illus

As place frem which they evidently
were originally torn, which fact will
lead us q step further, suggest the
presence Of granite also in American
Fork "a underlying the ssdlmentary
rock. The character OF the eres Of
American Fork and Silver Lake is
the same as in the Cottonwoods, and
are as follows: Galsna, car.
Donates of lead. chlorides, bro
mides and sulphates OF silver;
ochreous earth, iron, porous quartz
constitute the majority of the
vein material or gauge as a result of
the oxidation of argen!iferous and
auriferous minerals. The most char
acteristic ores are: Galena, cerus-
site, silver glance, copper glance and
free gold. The componeuts of the
ore are numerous and comprises: Ga
lena, sphalerite. pyrites. amesonite,
wad, anglesite, boulanger-
lite, cervantite, crocoise, cotunnite,
bromyrite, miLaetite, stephanite and
kaolin.
American Fork and the Cotton
woods show unmistsksble evidence
that they were at remote, past ages,
filed to their very mouth by glaciers.
Thsse glaciers can be easily traced
by the marks they lef! all over the
districts. 1t is indisputably a fact
that the system OF glaciers was coin.
