View of the elevated trough used to carry excavated rock and debris waste from Bucyrus No. 4 gold dredge, on the Swan River, east of Breckenridge, Colorado. Circa early 1900s.

A well-dressed man, woman, and boy stand on lumber scattered on the side of the Swan River, overlooking Bucyrus No. 4 dredge. Behind the boy is a large stack of wood for the dredge's boiler. Excavated rocks and boulders line the opposite side of the river, following the dredging route. In the background are tree-covered hills. Circa early 1900s.

Quoted from handwritten text on the item: "Remains of Gold Dredge in Swan River". The Bucyrus Dredge No. 4 began working on the lower Swan River north of Breckenridge in August 1899 and ceased operations sometime in the 1900s.
