Description: These massive dredges were designed to recover millions of dollars worth of gold from Northern California's ancient river bottoms. During the late 1800s and early 1900s, many people called them land-going ships because they floated across the otherwise dry landscape in their own self-made ponds. The dreadge featured here, one of the very last to operate, coud handle 18 cubic feet of river gravel per minute, sortign, separating, and processing the muck to extract gold. You see the dredge in operation, and also view the ongoing maintenance necessary to keep it going. Originally powered by steam, later dredges used diesel-electric power plants. They relied on river water for sluicing and separating the dredged material. Cyanide processing was done right on board the dredge. The dredge depicted in this film could process 90,000 cubic yards of river gravel every week -- enough (in good times) to produce a 30-pound gold ingot. Time -- 16 minutes 27 seconds Written and produced by: Arthur S. Hough Photography by: William Helck Edited by: Roy Nolan Directed by: David D. Grieve Original film production: 1973 Distributed by California Department of Parks and Recreation Publications Section. / © California Department of Parks and Recreation. All rights reserved. 1993.
