Gold Dredge No. 8 history
Gold Dredge No.8 represents an exciting part of the history of
development in the Northwest. The dredge is a reminder of the "gold
fever" that swept the nation and lured miners and entrepreneurs into the
frontiers of Alaska.
On July 22, 1902, Felix Pedro discovered gold on
Pedro
Creek, 16.5 miles northeast of Fairbanks. Pedro's
discovery launched a gold rush in the area which resulted in other
discoveries and the establishment of camps on Goldstream, Cleary, Ester
Dome, Eldorado, Fish, Fairbanks,
and Vault Creeks.
During the years following Pedro's discovery, numerous small mining
ventures used placer and crude underground mining methods to extract
nearly $7 million worth of gold. Mining operations were limited to the
winter months when tunnels could be kept dry. By 1920, miners had
exhausted the supply of readily accessible gold.
In that same year, Fairbanks Exploration Company entered the field north
of Fairbanks and acquired large blocks of
already-worked claims. The organization invested an additional $10
million in equipment and in construction of the Davidson Ditch which
delivered water to the mine sites and allowed for the operation of eight
giant dredges.
One of those eight dredges, Dredge No.8 was manufactured in 1927-28 by
Bethlehem Steel Company, Ship Building Division. The equipment was
shipped from Pennsylvania by transcontinental railroad and by
ocean-going barge to the Alaskan Railroad to be assembled in early 1928
just west of Fox, Alaska at the head of
the Goldstream Valley.
Gold Dredge No.8 has a 43 foot 9 inch high bow-gantry which supported
the belt-driven bucket line, with its 68 manganese steel buckets, each
with a capacity of 6 cubic feet and weight of 1,583 pounds. The buckets
were mounted on a steel digging ladder which measured in excess of 84
feet. The bucket line discharged gravel in to a dump-hopper to a
belt-driven trommel-screen, where perforations ranging in size from 3/8
to 1-5/8 inches, sized the gravel. During the process, an occasional
large nugget would stick in the screens as the dredged material traveled
down a gentle decline. In the trommel, the relatively heavy gold fell
through the screens; the rocks and gravels passed onto a conveyor belt
to be discharged. Nozzles inside the trommel drum were used to wash the
gold from the gravel before it was carried by a steel-reinforced
conveyor belt to the tailing pile behind the dredge. This process
resulted in removal of approximately 97 percent of the gold from the
rich gravels.
It operated each year until 1959.
The dredge is one of a string of floating gold dredges that operated in
the Goldstream Valley
in the middle of the last century.
The five-deck, 250-foot dredge was built in Goldstream and spent 32
years traveling up Lower Goldstream Creek to Engineer Creek and back –
more than 13 miles – scooping up hundreds of thousands of ounces of gold
as it went. It was one of
four dredges operated by the F.E. Co. in the area and was the only one
to spend its entire production life in Goldstream.
