Ringbolt Rapids are a series of rapids in the upper Black Canyon of the Colorado, 12 miles above the Roaring Rapids in the Colorado River between Arizona and Nevada. [1]
The Ringbolt Rapids were one of two of the significant hazards to navigation to steamboats, barges, and other shipping when ascending or descending the Colorado River between El Dorado Canyon and Callville, in the 19th Century. [2] :47, 49 Ringbolt Rapids gets its name from the ring bolt driven into the canyon wall there in 1866, to allow the pioneering steamboat Esmerelda to affix a line to it and draw itself up through the rapids by means of its capstan, to complete its voyage to Callville.

The Colorado River is one of the principal rivers in the Southwestern United States and northern Mexico. The 1,450-mile-long (2,330 km) river drains an expansive, arid watershed that encompasses parts of seven U.S. states and two Mexican states. Starting in the central Rocky Mountains of Colorado, the river flows generally southwest across the Colorado Plateau and through the Grand Canyon before reaching Lake Mead on the Arizona–Nevada border, where it turns south toward the international border. After entering Mexico, the Colorado approaches the mostly dry Colorado River Delta at the tip of the Gulf of California between Baja California and Sonora.
Lake Mead is a man-made lake that lies on the Colorado River, about 24 mi (39 km) from the Las Vegas Strip, southeast of the city of Las Vegas, Nevada, in the states of Nevada and Arizona. It is the largest reservoir in the United States in terms of water capacity. Formed by the Hoover Dam on September 30, 1935, the reservoir serves water to the states of Arizona, California, and Nevada, as well as some of Mexico, providing sustenance to nearly 20 million people and large areas of farmland.
The Black Mountains, a mid-Miocene formation, in Nevada are a series of rugged, arid rocky volcanic mountains ranging in elevations to 3310 ft. The range lies on the north shore of Lake Mead, at the southwest corner of the Overton Arm, about 25 mi south of Overton, Nevada.
Joseph Christmas Ives was an American soldier, botanist, and an explorer of the Colorado River in 1858.
El Dorado Canyon is a canyon in southern Clark County, Nevada famed for its rich silver and gold mines. The canyon was named in 1857 by steamboat entrepreneur Captain George Alonzo Johnson when gold and silver was discovered here. It drains into the Colorado River at the former site of Nelson's Landing.
Callville Bay is a waterway on the northwestern side of Lake Mead in the U.S. state of Nevada. It features a marina and camping resort. Situated east of Las Vegas and upstream from Las Vegas Bay, it lies within the Lake Mead National Recreation Area, which was established in 1935. Its name derives from the settlement of Callville which was established in 1865 by Anson Call under a directive led by Brigham Young. Though the settlement was abandoned in 1869, and submerged under Lake Mead when the Colorado River was dammed, Callville Bay retained the name.
Callville is a former settlement of Clark County in the U.S. state of Nevada. Abandoned in 1869, it was submerged under Lake Mead when the Colorado River was dammed, Callville Bay retaining the name. At one time, it was noted to be the southernmost outpost of the Mormon settlement.
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.
Esmerelda, was a stern-wheel paddle-steamer, built for the Sacramento River trade, in 1864 it became the first of the opposition steamboats on the Colorado River. It was also the first steamboat to tow large cargo barges on that river, in May 1864 and to reach Callville, Nevada in 1866.
Roaring Rapids are one of several rapids in the Black Canyon of the Colorado, 10.25 miles above El Dorado Canyon in the Colorado River between Arizona and Nevada.
Stone's Ferry is a former Mormon settlement and ferry crossing of the Colorado River between Nevada and Arizona, in Clark County, Nevada, United States.
Boulder Canyon, originally Devils Gate Canyon, is a canyon on the Colorado River, above Hoover Dam, now flooded by Lake Mead. It lies between Clark County, Nevada and Mohave County, Arizona. It heads at western end of the Virgin River Basin of Lake Mead, at about 36°09′05″N114°32′51″W. Boulder Canyon divides the Black Mountains into the Black Mountains of Arizona, and the Black Mountains of Nevada. Its mouth is now under the eastern end of the Boulder Basin of Lake Mead, between Canyon Point in Nevada and Canyon Ridge in Arizona. Its original mouth is now underneath Lake Mead between Beacon Rock and Fortification Ridge on the southern shore in Arizona.
Cottonwood Island, a large island in the Colorado River, within Cottonwood Valley, in Clark County, Nevada. Cottonwood Island was a low-lying island about 10 miles long and up to 3 miles wide. It was forested by cottonwoods and also after the spring flood, cluttered with driftwood from the riparian woodlands along the upper watershed of the Colorado River, washed down and caught in the first wide valley where the river slowed and spread out. Cottonwood Island was important as a source wood and of fuel for steamboats on that river and for the early mills and mines in El Dorado Canyon.
Gila, a stern-wheel steamboat of the Colorado Steam Navigation Company running on the Colorado River between 1873 and 1899.
Explorer's Rock was a large rock in the Colorado River that was a hazard to navigation at the mouth of the Black Canyon of the Colorado between Arizona and Nevada during the 19th century. It got its name from incident where the iron hulled steamboat Explorer struck it doing some damage, during the expedition of Lieutenant Joseph C. Ives, Corps of Topographical Engineers to explore the Colorado River of the West in 1857 and 1858.
George A. Johnson & Company was a partnership between three men who pioneered navigation on the Colorado River. Benjamin M. Hartshorne, George Alonzo Johnson and Alfred H. Wilcox. The George A. Johnson & Company was formed in the fall of 1852, and was reorganized as the Colorado Steam Navigation Company in 1869.
Callville Wash is an ephemeral stream or wash in Clark County, Nevada. It was named for Callville the riverport settlement founded in 1866, at its mouth where it had its original confluence with the Colorado River.
Cottonwood Spring is a spring in the Black Mountains between western end of Pinto Valley and Callville Wash. It lies at an elevation 2205 feet / 672 meters.
Boulder Wash is an ephemeral stream or wash in Clark County, Nevada. Its mouth is at its confluence with the Boulder Wash Cove of Lake Mead at an elevation 1,276 feet / 389 meters at when Lake Mead is at its full level. Currently as the reservoir is at a much lower level its mouth is found at approximately 36°10′07″N114°33′07″W. Its source is at 36°13′36″N114°31′22″W at an elevation of 2,841 feet / 866 meters in the Black Mountains. It flows down a canyon into the upper Pinto Valley southwestward before turning southeastward to Boulder Wash Cove.
