Francisco Vázquez de Coronado y Luján (1510 – 22 September 1554) was a Spanish conquistador and explorer who led a large expedition from Mexico to present-day Kansas through parts of the southwestern United States between 1540 and 1542.
 Vázquez de Coronado had hoped to reach the Cities of Cíbola, often referred to now as the mythical Seven Cities of Gold, which is a term not invented until American gold-rush days in the 1800s.
 His expedition marked the first European sightings of the Grand Canyon and the Colorado River, among other landmarks.
 His name is often Anglicized as "Vasquez de Coronado".
Located directly downstream of the Little Colorado River confluence with the Colorado River, the Tanner Graben, in the Grand Canyon, Arizona, USA is a prominence and cliffside rock formation below the East Rim.
 Tanner Graben is located riverside, on the Colorado River, on a north-northwest bank at Mile 68.5, and lies opposite Tanner Canyon.
 The Tanner Rapid, created by Tanner Creek lies at the riverside foot of the graben.
 The graben is a pronounced feature because of the black Cardenas Basalt that forms the middle section of the graben, presumably free of debris accumulation by its cliff face steepness, and winds, and airflow drainage that course through the Colorado River's canyons; unprotected side canyons of Cardenas Basalt show accumulations as a slope-forming geologic unit, with little showing of black basalt.
Port Isabel was a seaport established on Port Isabel Slough in 1865 during the American Civil War in Sonora, Mexico in the mouth of the Colorado River on the Gulf of California.
 It was founded to support the increased river traffic caused by the gold rush that began in 1862 on the Colorado River and the Yuma Quartermaster Depot newly established in 1864 to support the Army posts in the Arizona Military District.
 The slough was discovered in 1865 by the Captain W. H. Pierson of the schooner "Isabel", that first used the slough to transfer its cargo to steamboats safe from the tidal bore of the Colorado River.
 Shortly afterward Port Isabel was established 3 miles up the slough and replaced Robinson's Landing as the place where cargo was unloaded in the river from seagoing craft on to flat bottomed steamboats of the Colorado River and carried up to Fort Yuma and points further north on the river.
This is a list of adjoining wilderness areas for the "Lower Colorado River Valley".
 The List of "Lower Colorado River Valley" Wilderness Areas (Colorado River) is separated into the west side of the Colorado River: California-Nevada–and the east side of the Colorado River: for Arizona.
The Bill Williams River is a 46.3 mi river in west-central Arizona where it, along with its tributary, the Santa Maria River, form the boundary between Mohave County to the north and La Paz County to the south.
 It is a major drainage westwards into the Colorado River of the Lower Colorado River Valley south of Hoover Dam and Lake Mead, and the drainage basin covers portions of northwest, and west-central Arizona.
 The equivalent drainage system paralleling the east–west lower reaches of the Bill Williams is the Gila River, which flows east-to-west across central Arizona, joining the Colorado River in the southwest at Yuma.
 The confluence of the Bill Williams River with the Colorado is north of Parker, and south of Lake Havasu City.
Vidal Valley is a 20-mile (32 km) long valley in the far eastern Colorado Desert bordering the Colorado River.
 Most of the valley is in eastern San Bernardino County, California, but the outfall on the Colorado River is in northeast Riverside County.
 Vidal Valley forms the large border of the south side of the east-west block of the Whipple Mountains massif, the landform that forces the Colorado to flow southeast, then back southwest.
 The southeast exit of the valley into Parker Valley on the Colorado River skirts the north end of the Riverside Mountains (see photo).
 The Colorado River Aqueduct crosses the midpoint of the valley at Vidal Junction, California.
 The Vidal Valley also lies due east of the Danby Dry Lake landform.
The Tiguex War was the second named war – after the Battle of Mabila Oct 1540 – between Europeans and Native Americans in what is now the United States.
 It was fought in the winter of 1540-41 by the expedition of Francisco Vázquez de Coronado against the twelve or thirteen pueblos of Tiwa Indians as well as other Puebloan tribes along both sides of the Rio Grande, north and south of present-day Bernalillo, New Mexico, in what was called the Tiguex Province.
 The only book-length treatment of the Tiguex War is in the historical novel, Winter of the Metal People.
The Trigo Mountains are a north-south trending mountain range in La Paz County, Arizona, bordering the Colorado River on the east in the Lower Colorado River Valley.
 The range lies north of the Colorado River as it turns east, north of Martinez Lake and the Imperial Reservoir.
 The Trigo Mountains are on a north-south stretch of the Colorado River, and form the eastern perimeter of the Imperial National Wildlife Refuge.
After a 1944 United States Mexico Treaty the Morelos Dam was built in 1950 across the Colorado River.
 It is located about 1 mi below the junction of the California border and the Colorado River between the town of Los Algodones, Baja California, in northwestern Mexico and Yuma County, Arizona in the southwestern United States.
 The eastern half of the dam lies inside United States territory; but Mexico is responsible for all maintenance.
 The dam allows Mexico to divert its allotted water from the Colorado River to highly developed crop lands in the Mexicali, Mexico Valley.
 The Morelos Dam is the final dam on the Colorado River.
 It is run by the International Boundary and Water Commission (IBWC).
The Lower Colorado River Valley ("LCRV") is the river region of the lower Colorado River of the southwestern United States in North America that rises in the Rocky Mountains and has its outlet at the Colorado River Delta in the northern Gulf of California in northwestern Mexico, between the states of Baja California and Sonora.
 This north–south stretch of the Colorado River forms the border between the U.S. states of California and Arizona, and Nevada and Arizona; also between the Mexican states of Baja California and Sonora.
