Auburn. It was principally surface mining.
A great deal of ravine mining has been done
there by Cinnamon. There is some mining
going on there in Junction ravine. The ma
tsrial from all that mining has been dis
charged into the North Fork Of the Amer
lean river, through its tributaries.
Q-Do you know how much ground has
been worked in the Iowa Hill DISTRICT
Ayes, sir. i made an estimate of how
much was worked some time ago. My mem
DRY is not good, and if you will allow me to
use my notebook | can tell you.
Q.-State what you mean by the Iowa
Hill district.
A.-That includes the district extending
from Kings Hill, on the west, TO Secret can
yon, on the east, and from Shirt-taIl canyon,
on the south, to the North Fork Of the
American-s district about twenty-five miles
in length it varies III width. The area COW
cred by mining claims and mining locations is
about thirty square miles, embraced in what
is called Iowa Hill district. The ground that
has been washed off covers an area of 35S
acres / ascertaiued that fact by measure
ments. The depth to which it Is washed va
ries In cubic yards, according to my meas
urement, it would be 36, 06S 600 cubic yards.
| There has been washed into Indian canyon
since / went there 81 acres. Indian canyon
empties into the North Fork below Rice's
amounts to 1855 500 That is since 1878. /
washed in. Of that, 100000 yards from the
Independence Hill mine.
Q-What mines discharge into Indian
creek?
A.-Phere are mines a. Iowa Hill proper,
on the Morning Star Hill, Pritohards Hill,
portions of IndependeI &c Hill, and portions
| of what Is known as Wisconsin Hill and Eliz-
abethtown. The tailiugs are dumped into
! NfoN 80
| the North Fork. | cannot say exactly to
what extent that canyon has filed up with
tallings, only what | know since I have been
there. There is one point there where am
confident it has filed sixty feet since 1 have
been there. There are larger or heavier fill
ines below, bat / DO not know exactly what
the depth of them is.
Q-What mines discharge into the North
! Fork between Canyon creek and Stevenson's
bridge, from the Iowa Hill district, since you
| have been thers?
A-The Wolverine Aurora, Pritchard,
independence Hill and Booth at Iowa Hill.
| Booth worked one season, the Wolverine two
seasons, the Aurora two seasons the Pritch-
ard three seasons. the Union one and the
Independence Hill claim three seasons.
am speaking of since 1878. TIE Wolverine
and Aurora were formerly worked by drift
ing. Since l have been there thew are worked
by the hydraulic process. The total area OF
excavations there is Z, OBS. 600 cubic wards.
The mines that discharge into the North
Fork [ estimate use 9 500 inches OF water per
per day for 100 DAYS. The material from
these mines has he effect of filing the North
Fork. Since 1873 it has filed at Warmers
bridge thirty feet. At the Blue Wing CANYON
it has filed up thirty feet that is a mile be-
low Warmers bridge. think it has filed
little more than that opposite what is known
as HObsOn's CANYON, Our mine DISCHARGES
into that canyon. 1t has the effect Of
damming the river to a certain extent
and causing the tailings from above to lodge
and deposit; it raises the flow Of water and
sets the water back several hundred feet
There has been one freshet since I have been
there-thst of 1881. The material that we
put in is composed of powders, the largest
fifteen feet IN diameter and down to silt. We
find the powders in the top soil it is OF
volcanic character. The wash-bowlders are
found in the gravel near the bedrock. The
volcanic powders are broken no and run
through the fume in as large pieces as will
60 through From Rice's bridge TO the head
of chickering's Bar the average depth Of tail
ings in November was estimated at Eve yards
deposited since / went there There is a
difference between the sand from Gold RIM
and that from Iowa Hill. The extent of
ground located in the Iowa Hi district is
Is. 200 acres. If 1 were going to purchase for
hydraulic purposes | would not take more
than 200 acres of that.
Q.-HOw must the remaining portion Of
this is 200 acres be mined?
A.-By the means of drifting and after
wards hydrsulieking; that is, the dirt is first
drifted and dumped into dump, and there
washed by the hydraulic process
