Basin is an unincorporated community and census-designated place (CDP) in Jefferson County, Montana, United States. It lies approximately 10 miles (16 km) southeast of the Continental Divide in a high narrow canyon along Interstate 15 about halfway between Butte and Helena. Basin Creek flows roughly north to south through Basin and enters the Boulder River on the settlement's south side. The population was 212 at the 2010 census, down from 255 at the 2000 census.
The Tuolumne River flows for 149 miles (240 km) through Central California, from the high Sierra Nevada to join the San Joaquin River in the Central Valley. Originating at over 8,000 feet (2,400 m) above sea level in Yosemite National Park, the Tuolumne drains a rugged watershed of 1,958 square miles (5,070 km2), carving a series of canyons through the western slope of the Sierra. While the upper Tuolumne is a fast-flowing mountain stream, the lower river crosses a broad, fertile and extensively cultivated alluvial plain. Like most other central California rivers, the Tuolumne is dammed multiple times for irrigation and the generation of hydroelectricity.
The Comstock Lode is a lode of silver ore located under the eastern slope of Mount Davidson, a peak in the Virginia Range in Virginia City, Nevada, which was the first major discovery of silver ore in the United States and named after American miner Henry Comstock.
A flume is a human-made channel for water, in the form of an open declined gravity chute whose walls are raised above the surrounding terrain, in contrast to a trench or ditch. Flumes are not to be confused with aqueducts, which are built to transport water, rather than transporting materials using flowing water as a flume does. Flumes route water from a diversion dam or weir to a desired materiel collection location. Flumes are usually made up of wood, metal or concrete.
The Kaweah River is a river draining the southern Sierra Nevada in Tulare County, California in the United States. Fed primarily by high elevation snowmelt along the Great Western Divide, the Kaweah begins as four forks in Sequoia National Park, where the watershed is noted for its alpine scenery and its dense concentrations of giant sequoias, the largest trees on Earth. It then flows in a southwest direction to Lake Kaweah – the only major reservoir on the river – and into the San Joaquin Valley, where it diverges into multiple channels across an alluvial plain around Visalia. With its Middle Fork headwaters starting at almost 13,000 feet (4,000 m) above sea level, the river has a vertical drop of nearly two and a half miles (4.0 km) on its short run to the San Joaquin Valley, making it one of the steepest river drainages in the United States. Although the main stem of the Kaweah is only 33.6 miles (54.1 km) long, its total length including headwaters and lower branches is nearly 100 miles (160 km).
The Marlette Lake Water System was created to provide water for the silver mining boom in Virginia City, Nevada. These structures are now listed as a National Historic Civil Engineering Landmark by the American Society of Civil Engineers, and are also listed on the National Register of Historic Places. The listed area included two contributing buildings and 12 contributing structures on 135.4 acres (54.8 ha). It has also been known historically as the Virginia and Gold Hill Water Company Water System.
The North Bloomfield Mining and Gravel Company of North Bloomfield, California, was established in 1866 and operated a hydraulic gold-mining operation at the Malakoff Mine subsequent to the California Gold Rush. In its day, no other company's operations matched North Bloomfield Mining and Gravel Company in size or expense. The company operated until 1910. In the years prior, its profits and procedures had been reduced due to the landmark ruling of Woodruff v. North Bloomfield Gravel Mining Company.
The Bighorn Ditch Headgate, also known as the Bighorn Canal Headgate, was built starting in 1892 to provide irrigation to the Crow Indian Reservation in south central Montana. The headgate structure diverted water from the Bighorn River to their lands. It was designed by William F. Graves, and construction was carried out by Crow workers. The project was completed in 1904. Today the site is included in Bighorn Canyon National Recreation Area.
The Whisky Creek Cabin is a rustic log cabin located in southwest Oregon along the section of the Rogue River that is designated as a National Wild and Scenic River. It is the oldest remaining mining cabin in the Rogue River canyon. The Bureau of Land Management purchased the cabin and surrounding property in 1973. The Whisky Creek Cabin is listed on the National Register of Historic Places in 1975.
Leesburg is an unincorporated community in Lemhi County, Idaho, United States. It lies at 45°13′26″N114°6′50″W, along Napias Creek in the Salmon National Forest, west of Salmon. Its altitude is 6,653 feet (2,028 m).
The Osceola Ditch, also known as the East Ditch, was built in 1889–1890 to convey water from Lehman Creek, Nevada to a hydraulic mine operation at Osceola. Extending for 18 mi (29 km), the ditch includes a 600 ft (180 m) tunnel as well as wooden flumes. The project also includes a rock dam and headgate on Stella Lake. The ditch's terminus at Osceola, Nevada became disused during the early 1900s and was destroyed entirely by a fire in the 1940s. Much of the East Ditch is included within Great Basin National Park.
The historical buildings and structures of Zion National Park represent a variety of buildings, interpretive structures, signs and infrastructure associated with the National Park Service's operations in Zion National Park, Utah. Structures vary in size and scale from the Zion Lodge to road culverts and curbs, nearly all of which were designed using native materials and regional construction techniques in an adapted version of the National Park Service Rustic style. A number of the larger structures were designed by Gilbert Stanley Underwood, while many of the smaller structures were designed or coordinated with the National Park Service Branch of Plans and Designs. The bulk of the historic structures date to the 1920s and 1930s. Most of the structures of the 1930s were built using Civilian Conservation Corps labor.
Confederate Gulch is a steeply incised gulch or valley on the west-facing slopes of the Big Belt Mountains in the U.S. state of Montana. Its small stream drains westward into Canyon Ferry Lake, on the upper Missouri River near present-day Townsend, Montana. In 1864, Confederate soldiers on parole during the American Civil War made a minor gold discovery in the gulch, but the discovery of the sensationally rich Montana Bar the following year—one of the richest placer strikes per acre ever made—led to other rich gold strikes up and down the gulch, and touched off a frantic boom period of placer gold mining in the area that extended through 1869. From 1866 to 1869, the gulch equaled or outstripped all other mining camps in the Montana Territory in gold production, producing an estimated $19–30 million worth of gold. For a time, Confederate Gulch was the largest community in Montana. In 1866, Montana had a total population of 28,000, and of these, about 10,000 (35%) were working in Confederate Gulch.
The Hanging Flume was an open water chute 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.
The Middle Fork American River is one of three forks that form the American River in Northern California. It drains a large watershed in the high Sierra Nevada west of Lake Tahoe and northeast of Sacramento in Placer and El Dorado Counties, between the watersheds of the North Fork American River and South Fork American River. The Middle Fork joins with the North Fork near Auburn and they continue downstream to Folsom Lake as the North Fork, even though the Middle Fork carries a larger volume of water.
Vicksburg was a town and mining camp in Chaffee County, Colorado, high in Clear Creek Canyon. It is now effectively a ghost town, although some of the buildings may be seasonally occupied by their owners. The site was listed on the National Register of Historic Places in 1977 ; a part of the town is maintained by the Chaffee County Historical Society as a museum. Four miles farther up the same road on which Vicksburg is located is another old mining camp named Winfield.
The China Ditch in Douglas County, in the U.S. state of Oregon, was a 30-mile (48 km) canal built in part by Chinese laborers to supply water for the hydraulic mining of gold. The Myrtle Creek Consolidated Hydraulic Gold Mining and Manufacturing Company began purchasing land for the ditch in 1890 and was bankrupt by 1894. Portions of the ditch, which carried water from Little River to North Myrtle Creek, remain visible, and an 11-mile (18 km) section is listed on the National Register of Historic Places.
The Independence Trail is located approximately 7 miles from downtown Nevada City within the South Yuba River State Park in the Sierra Nevada foothills within Nevada County, in Northern California. The trail is the former Excelsior Ditch, which was found and repaired by John Olmsted and a large group of local volunteers. It is notable for being the first ADA approved wheelchair nature trail. It topped the list of "favorite trails for 2013" in The Sacramento Bee newspaper.
Crow Creek is a stream in the Chugach Mountains, Alaska, US. It is the only notable tributary of Glacier Creek, which enters Turnagain Arm from the north, 12 miles (19 km) from its eastern end. The stream is notable as the site of ongoing gold mining since the late 19th century.
The Fairhaven Ditch is a historic canal on the Seward Peninsula of northwestern Alaska. Located in the Bering Land Bridge National Preserve, it is a 38-mile (61 km) ditch dug in 1906-07 without the benefit of heavy equipment in extremely hostile terrain. The ditch was dug by miners engaged in placer mining on the peninsula, and was used to transport water from Imuruk Lake, the largest body of fresh water on the peninsula, to mining areas north of the lake. It is one of a large number of such canals dug on the peninsula, and was one of the longest. At the bottom it was 11 feet (3.4 m) wide, and was hacked out of permafrost, a volcanic field surrounding the lake, and dirt. Cabins built to house workers and monitor water flow survive. The ditch was listed on the National Register of Historic Places in 1987.
