The remaining 24 miles (39 km) miles of the flume followed the river into Sanger. Construction was completed on September 3, 1890. [7] [10] Workers load blocks of lumber into the flume. To load the flume, sawmill workers trimmed logs into planks and clamped them into blocks. The blocks were then linked together to form trains.
Early logging flumes were square wooden chutes known as box flumes. These were prone to jams that could cause damage and required constant maintenance. They were also costly to build. A square box carries much more water compared to a V-shaped flume. The greater weight of the water required a sturdier structure, especially heavier trestles.
The Hanging Flume was an open water chute (known as a flume) built over the Dolores River Canyon in Colorado. The Montrose Placer Mining Company built the flume in the 1880s to facilitate gold mining. Some sections of the flume remain attached to the canyon wall, although much of the wood has vanished. [2]
Some varieties of flumes are used in measuring water flow of a larger channel. When used to measure the flow of water in open channels, a flume is defined as a specially shaped, fixed hydraulic structure that under free-flow conditions forces flow to accelerate in such a manner that the flow rate through the flume can be characterized by a level-to-flow relationship as applied to a single head ...

A chute, also known as a race, flume, cat, or river canyon, is a steep-sided passage through which water flows rapidly. Akin to these, man-made chutes, such as the timber slide and log flume, were used in the logging industry to facilitate the downstream transportation of timber along rivers. These are no longer in common use.
The Cordero Rojo Mine is a coal mining complex located in the state of Wyoming in the United States, in the coal-rich Powder River Basin.The mine is of open pit construction and employs several dragline excavators.
The Black Thunder Coal Mine is a surface coal mine in the U.S. state of Wyoming, located in the Powder River Basin which contains one of the largest deposits of coal in the world. In 2022, the mine produced 62,180,000 short tons (56,410,000 t) of coal, [ 1 ] over 25% of Wyoming's total coal production.
