ridge of the range. Treasure Hill is
a -quaquaversal uplift of the Ne
yada'. tDevonian) limestones and
White Pine shales, with its longest
axis north and south. White Pine
mountain is topped with the lower
Silurian or "Pogonip" formation and
at it's west base exposes about LOCO
feet of Cambrian states and lime
stones. A great fault running along
the west base of the mountain and
another at the north end bring the
Carboniferous strata of the desert in
juXtaposition with the Cambrian and
Silurian of the mountain, showing a
displacement of probably 10000 feet.
Within the district are numerous
faults and folds of minor displace-
ment and intensity which impart the
rugged and irregular topography.
The normal position and thickness
of the sediments here is as follows:
Starting with 1000 feet of exposed
Cambrian limestones and states at
the base and naming them in ascend
ing order: 1000 feet of Cambrian;
$500 feet of "Pogonip" limestone:
$50 feet of Eureka %quartite; 1900

(Silurian) 1000 feet of Nevada
limestone; 1900 feet of white
Pine" shale (Devonian;) 200 feet of
sandstone and 1000 feet of lime
stone, (Carboniferous;) making a
total thickness of nearly $4,000 feet.
There are three distinct mineral
ranges or belts in the district; the
silver belt, at the top of the Nevada
limestone and beneath the White
Pine shale, running north and south
from Treasure Hill; the copper belt
OF the west side of the mountain in
the igneous rock and the Cambrian;
and the lead belt or Base Metal
range, about half way between the
summit of the "Pogonip' and the
Nevada limestone.
There are three fault systems.
First, an east west system; second a
north southeast dipping system; and
third, a north-southwest dipping sys-
tenn observable about 300 feet below
the surface in the mines of Rocco
Canyon.
The most striking feature of the
silver deposits were their great rich
ness at the surface and their CON-
paratively shallow depth. Hague,
in his description of the district
United States Survey of 10th Par
allel, Vol. 3, page 41S,) notes foul
different kinds of veins or deposits
on Treasure Hill, and while the ores
do occur in all the positions he des-
cribes it is the opinion of mining
men today that the Saddle reef
theory will them all. Treasure
Hill Is an anticlinal dome, mainly
composed Of Nevada limestone, but
the White Pine shale is, in areas,
still left in it's correct position over
lying it. A great fault runs east
the hill, passing a little north. of
S~hermantown and extending to
White Pine mountain. A north and
south fault runs along the axis of
the fold and divides the southern
end of the crest of the hill into two
parts, n part running easterly
through the Hidden Treasure mine,
and one running n%ortherly along the
western side of the hill, extending,
beyond the north end of it over three
miles where 1t disappears in a fold.
This is known as the Treasure Hill
fault. There are also
minor faults and tension cracks. At
the time of the uplift the shale
covered the limestone. The lime
stone, being brittle, was shattered,
but the shales being more yielding
and flexible bent to a considerable
degree and formed an impervious
roof. The silver bearing solutions
coming up along the faults and
breaks in the lime were arrested
upon striking the shales and COM
