Charles H. Spencer Hulk
The ''Charles H. Spencer'' was a Paddle steamer#Types of paddle steamer, stern-wheel steamboat that was briefly used on the Colorado River to transport coal for gold refining operations at Lee's Ferry, Arizona. In 1910, Charles H. Spencer was a prospector who arrived at Lee's Ferry in search of gold hidden in shale of the Chinle Formation. His company, American Placer Corporation, processed the shale by creating a mud and then removing the gold deposits by Amalgam (chemistry), mercury amalgamation, which required a steady source of power. Finding a coal seam up river, Spencer commissioned a San Francisco company, Robertson–Schultz Co., to build the stern-wheel, stern-wheel paddle steamer, ''Charles H. Spencer'', for the American Placer Corporation. James Robertson and Herman Rosenfelt built the ship. It was 92.5 feet long, 25 feet abeam and had a draft of 18 to 20 inches.

Lee's Ferry
Lees Ferry (also known as Lee's Ferry, Lee Ferry, Little Colorado Station and Saints Ferry) is a site on the Colorado River in Coconino County, Arizona in the United States, about southwest of Page, Arizona, Page and south of the Utah–Arizona state line. Due to its unique geography – the only place in hundreds of miles from which one can easily access the Colorado River from both sides – it historically served as an important river crossing and starting in the mid-19th century was the site of a ferry operated by John Doyle Lee, for whom it is named. Boat service at Lees Ferry continued for over 55 years before being superseded by a bridge in the early 20th century, which allowed for much more efficient automobile travel. Lees Ferry served as a military outpost for 19th-century settlements in Utah, a center of limited gold seeking and since the 1920s the principal point at which river flow is measured to determine water allocations in the Colorado River basin.

Steamboats Of The Colorado River
Steamboats on the Colorado River operated from the river mouth at the Colorado River Delta on the Gulf of California in Mexico, up to the Virgin River on the Lower Colorado River Valley in the Southwestern United States from 1852 until 1909, when the construction of the Laguna Dam was completed. The shallow draft paddle steamers were found to be the most economical way to ship goods between the Pacific Ocean ports and settlements and mines along the lower river, putting in at landings in Sonora state, Baja California Territory, California state, Arizona Territory, New Mexico Territory, and Nevada state. They remained the primary means of transportation of freight until the advent of the more economical railroads began cutting away at their business from 1878 when the first line entered Arizona Territory. Steamboats were tried on the upper Colorado River: in Glen Canyon; on the Green River in Utah and Wyoming; and on the Grand River, (renamed as the upper part of the Colorado R ...

Ships On The National Register Of Historic Places In Arizona
A ship is a large watercraft that travels the world's oceans and other sufficiently deep waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research, and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity, and purpose. Ships have supported exploration, trade, warfare, migration, colonization, and science. After the 15th century, new crops that had come from and to the Americas via the European seafarers significantly contributed to world population growth. Ship transport is responsible for the largest portion of world commerce. The word ''ship'' has meant, depending on the era and the context, either just a large vessel or specifically a ship-rigged sailing ship with three or more masts, each of which is square-rigged. As of 2016, there were more than 49,000 merchant ships, totaling almost 1.8 billion dead weight tons. Of these 28% were oil tankers, 43% were bulk carriers, and 13% were cont ...

History Of Coconino County, Arizona
Coconino County is a county in the north-central part of the U.S. state of Arizona. Its population was 145,101 at the 2020 census. The county seat is Flagstaff. The county takes its name from ''Cohonino'', a name applied to the Havasupai people. It is the second-largest county by area in the contiguous United States, behind San Bernardino County, California. It has , or 16.4% of Arizona's total area, and is larger than each of the nine smallest states in the U.S. Coconino County comprises the Flagstaff metropolitan statistical area, Grand Canyon National Park, the federally recognized Havasupai Nation, and parts of the federally recognized Navajo, Hualapai, and Hopi nations. As a result, its relatively large Native American population makes up nearly 30% of the county's total population; it is mostly Navajo, with smaller numbers of other tribes. The county was the setting for George Herriman's early 20th-century '' Krazy Kat'' comic strip. History After European Am ...

Marysvale, Utah
Marysvale is a town in Piute County, Utah, United States. The population was 408 at the 2010 census. Marysvale is a trail head for the Paiute ATV Trail. History A post office called Marysvale has been in operation since 1872. The town's name probably commemorates the Virgin Mary. In the late 1860s, silver ore was discovered in the Volcanic Series of Bullion Canyon and Mount Belknap, west of Marysvale in the Tushar Mountains. In 1889, gold was discovered. Then in 1949, uranium was discovered, prompting the United States Atomic Energy Commission to establish an ore purchasing station and field office in Marysvale. The uranium occurs as veins within quartz monzonite, granite and rhyolite, usually in the form of pitchblende, but also as umohoite, which was first identified at Marysvale. The pitchblende has been age dated to the Late Miocene. Total uranium production from the Marysvale area amounted to about 275,000 tons of 0.2 per cent U2O8. Geography According to the Uni ...

Stern-wheel
A paddle steamer is a steamship or steamboat powered by a steam engine that drives paddle wheels to propel the craft through the water. In antiquity, paddle wheelers followed the development of poles, oars and sails, where the first uses were wheelers driven by animals or humans. In the early 19th century, paddle wheels were the predominant way of propulsion for steam-powered boats. In the late 19th century, paddle propulsion was largely superseded by the screw propeller and other marine propulsion systems that have a higher efficiency, especially in rough or open water. Paddle wheels continue to be used by small, pedal-powered paddle boats and by some ships that operate tourist voyages. The latter are often powered by diesel engines. Paddle wheels The paddle wheel is a large steel framework wheel. The outer edge of the wheel is fitted with numerous, regularly spaced paddle blades (called floats or buckets). The bottom quarter or so of the wheel travels under water. An engi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amalgam (chemistry)
An amalgam is an alloy of mercury with another metal A metal (from Greek μέταλλον ''métallon'', "mine, quarry, metal") is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. Metals are typicall .... It may be a liquid, a soft paste or a solid, depending upon the proportion of mercury. These alloys are formed through metallic bonding, with the electrostatic attractive force of the conduction electrons working to bind all the positively charged metal ions together into a Crystal structure, crystal lattice structure. Almost all metals can form amalgams with mercury, the notable exceptions being iron, platinum, tungsten, and tantalum. Silver-mercury amalgam (dentistry), amalgams are important in dentistry, and gold-mercury amalgam is used in the Gold extraction, extraction of gold from ore. Dentistry has used alloys of mercury with metals such as silver, copper, indium, tin a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chinle Formation
The Chinle Formation is an Upper Triassic continental geological formation of fluvial, lacustrine, and palustrine to eolian deposits spread across the U.S. states of Nevada, Utah, northern Arizona, western New Mexico, and western Colorado. In New Mexico, it is often raised to the status of a geological group, the Chinle Group. Some authors have controversially considered the Chinle to be synonymous to the Dockum Group of eastern Colorado and New Mexico, western Texas, the Oklahoma panhandle, and southwestern Kansas. The Chinle Formation is part of the Colorado Plateau, Basin and Range, and the southern section of the Interior Plains.GEOLEX database entry for Chinle USGS (viewed 19 March 2006) A probable separate depositional basin within the Chinle is found in northwestern Colorado and northeastern Ut ...

Shale
Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2 Si2 O5( OH)4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite.Blatt, Harvey and Robert J. Tracy (1996) ''Petrology: Igneous, Sedimentary and Metamorphic'', 2nd ed., Freeman, pp. 281–292 Shale is characterized by its tendency to split into thin layers ( laminae) less than one centimeter in thickness. This property is called '' fissility''. Shale is the most common sedimentary rock. The term ''shale'' is sometimes applied more broadly, as essentially a synonym for mudrock, rather than in the more narrow sense of clay-rich fissile mudrock. Texture Shale typically exhibits varying degrees of fissility. Because of the parallel orientation of clay mineral flakes in shale, it breaks into thin layers, often splintery and usually parallel to the otherwise indistinguishable beddin ...
