From the Nye County, Nevada Photograph Collection (PH-00221) -- Series VI. Tonopah, Nevada -- Subseries VI.D. Terrell Family. A pontoon from the dredge constructed at Manhattan, Nevada, prior to World War II. A large hole was dug to impound water. Water was then piped to Manhattan from across the valley at Peavine and fed into the hole. The superstructure was constructed atop the pontoon, and the dredge, with buskets in front, scooped the gravel out as it moved from the lower end of the gulch to the upper end, about 1-1/2 miles. The gravel that was scooped out was processed for gold on the dredge and fed out back of the dredge when processing was completed.
