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.
