BULLETIN ON
THE NELCHINA
MINING REGION
The Nelchina region came into
notice a few years ago by the dis
covery of placer gold on Albert creek,
one of the branches of Crooked creek,
a tributary of Little Nelchina river.
The geological survey has just is
sued a bulletin on the geology and
mineral resources of this district. The
region covered in this report includes
the placers of the Nelchina district
and extends north as far as the east
ward part of the Susitna river and
east to Copper Center.
The report describes twenty geo
logical formations that are found, and
traces in detail the geologic changes
and the development of the surface
forms, and occurrence of the placer
gold. The record indicates that the
oldest formation of the region was
deposited late in the Paleozoic era, at
which time a portion of this region
was submerged by the sea. The Me
sozoic era was marked by two periods
of volcanism and several of marine
sedimentation. That parts of the re
gion were covered by the sea during
this period is shown by the marine
animals the fossils of which are pre
served in the rocks at a great many
places. The first period of volcanism
was in Triassic time during which
several thousand feet of basic lavas
were poured out. Marine sedimenta
tion extended intermittently through
out the Jurassic period but was
broken by periods of igneous intru
sion, diastrophism and uplift of the
land above sea level, and consequent
denundation. It was during or just
after middle Jurassic time that the
magmas that formed the batholithic
masses of quartz diorite in the Tal
keetna mountains were injected.
. Marine sedimentation continued inter
mittently throughout the Cretaceous
period and was probably closed in
early Eocene time by a general uplift
of the land which brought this entire
region above the sea, which in the
main was a period of differential up
lift and degradation, including the
period of crustal deformation which
involved folding and deformation
along the Alaska, range. The first
stage of' tertiary history was one of
^,,.£eneral erosion which reduced the
land to a peneplain or near plain the
uplifted portions of which may be
now seen on the Talkeetna mountains.
It was during or following this stage
of planation that the fluviatile and
lacustrine coal-bearing rocks of Broad
pass, Matanuska valley and Cook inlet
were deposited. Following this period
of erosion was one of diastrophism
and uplift in which intense crustal de
formation occurred along the Alaska
range. In the Nelchina-Susitna region
this uplift was accompanied by fold
ing and igneous intrusion and a gen
eral outpouring of lava without
marked deformation.
The uplift was followed by another
cycle of erosion in which the major
features of the present surface were
outlined. The Talkeetna mountains
and the mountains north of Susitna
river were carved with uplifted
masses and the larger stream valleys
were formed. The Copper river which
now flows southeast toward Chitina
where it is joined by the Chitina river
at that time flowed in the opposite
direction, across the present gravel
covered Copper-Susitna lowland and
joined the Susitna river near the
mouth of Tyone river, thus ultimately
finding its way into Ccok inlet instead
of the Gulf of Alaska as at present,
its diversion was brought abour. by
the immense accumulations of glacial
ice in this basin which blocked the
drainage and caused the river to sock
a new channel. The steps by which
this was brought about are traced in
detail in the report.
The glaciation was probably coin
cdent with the general glaciation of
the region which was brought about
when the climate became favorable
for the continuous accumulation of
snow. The higher parts of the moun
tains became gathering places for
glacial ice, which moved along stream
courses as valley glaciers and as these
glaciers descended to the lowlands
they deployed to form piedmont ice
sheets and finally coalesced into a
great intermontane glacier which at
file time of its maximum intensity
spread from the Alaska range to the
Talkeetna and the Chugach moun
tains. It extended far up Chitina val
ley and included part of the Chulitna
and Wirangell mountains in its ice-cov
ered basin. This region is of interest
as it affords evidence of more than
one period of glaciation, proof of
which has been found in very few
places in Alaska as the glaciation of
the last period was so intense as to
remove traces of any former glacial
periods. The glaciation may appear
t obe of academic interest only, but
on the contrary in this region has a
very direct bearing on the accumula
tion and distribution ot tne placer
gold, the principal known mineral re
source of the region.
When the conditions became un
favorable for the continued accumula
tion of ice, so that the waste became
greater than the supply, a general re
treat of the glaciers began, which has
continued intermittently to the
present. During this period of glacial
retreat the great gravel sheet of the
Copper-Susitna basin was built up.
This gravel deposit, which in places is
over 1000 feet thick, was derived from
the debris dropped by the melting
glaciers and was spread out by the
glacial stream.
Placer gold is widely distributed
and may be found on nearly any
stream of the region.
CANADIAN CATTLEMEN
OBJECT TO QUARANTINE
OTTAWA, Ont., April 23 (by Asso
ciated Press).—Western Canadian
cattle raisers have made representa
tions to the dominion government
here, claiming that the sharp quaran
tine restrictions in the United States
have decreased their revenue.
Statements prepared by the ranch
ers say the American quarantine has
forced Canadian cattle men to dispose
of most of their stock at Winnipeg
where prices have averaged $2 to $3
a head less than in St. Paul, and that
the quarantine has placed the live
stock industry “in an intolerable posi
tion” in Manitoba, Saskatchewan and
Alberta.”

RHINELAND ESTATES
ARE OFFERED FOR SALE
COLOGNE, April 23 (by Associated
Press).—In recent newspaper adver
tisements an unusually large number
of villas and landed estate in the
Rhineland have been offered for sale
at "sacrifice” prices. Many of these
residences are on the hills along the
Rhine and are occupied only during
the summer months, the owners
having homes in Berlin, Frankfort,
Dresden and other cities of the In
terior. Most of those eager to sell
appear to be German nobles and
higher class public officials, prices
asked for these properties ranging
from 50,000 to 1,000,000 marks.
