Hanging Flume : ウィキペディア英語版 | Hanging Flume
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. ==Background==
The Montrose Placer Mining Company was formed to mine gold from placer deposits along the Dolores River. Hydraulic mining, a popular method of exploiting placer deposits, required water to be efficiently transported, often using wooden flumes to maintain the necessary volume and pressure. Cliffside flumes were developed in California, using trestles and brackets (called ''bents'') at regular intervals to support the flume box.〔 The flume connected with a six mile long ditch, both designed to provide water for miners in the San Juan Mountains of Colorado.
