Andrew Gray (surveyor)
Andrew Belcher Gray (July 6, 1820 – April 16, 1862) was an American surveyor. Born in Norfolk, Virginia, he studied engineering and surveying under Andrew Talcott, and surveyed the Mississippi Delta with him in 1839, before joining the Texas Navy as a midshipman. Remaining in the Republic of Texas, he was appointed a surveyor for the Texas-U.S. boundary commission led by Memucan Hunt. In 1844–1846, he served as U.S. government mineral surveyor, mapping the rich copper country of the Keweenaw Peninsula in Michigan and leasing out the government's mineral lands. He returned to the new state of Texas during the Mexican–American War. Following the war, he served as chief surveyor of the US–Mexican commission which established the border after the Treaty of Guadalupe Hidalgo. When the U. S. Commissioner, John Bartlett, a Yankee, gave away the Rio Grande's Mesilla Valley because of a map error, which had been disputed by the Mexican Delegation, the fiery Southerner Gray oppos ...

Surveying
Surveying or land surveying is the technique, profession, art, and science of determining the terrestrial two-dimensional or three-dimensional positions of points and the distances and angles between them. A land surveying professional is called a land surveyor. These points are usually on the surface of the Earth, and they are often used to establish maps and boundaries for ownership, locations, such as the designed positions of structural components for construction or the surface location of subsurface features, or other purposes required by government or civil law, such as property sales. Surveyors work with elements of geodesy, geometry, trigonometry, regression analysis, physics, engineering, metrology, programming languages, and the law. They use equipment, such as total stations, robotic total stations, theodolites, GNSS receivers, retroreflectors, 3D scanners, LiDAR sensors, radios, inclinometer, handheld tablets, optical and digital levels, subsurface locators, d ...

American Civil War
The American Civil War (April 12, 1861 – May 26, 1865; also known by other names) was a civil war in the United States. It was fought between the Union ("the North") and the Confederacy ("the South"), the latter formed by states that had seceded. The central cause of the war was the dispute over whether slavery would be permitted to expand into the western territories, leading to more slave states, or be prevented from doing so, which was widely believed would place slavery on a course of ultimate extinction. Decades of political controversy over slavery were brought to a head by the victory in the 1860 U.S. presidential election of Abraham Lincoln, who opposed slavery's expansion into the west. An initial seven southern slave states responded to Lincoln's victory by seceding from the United States and, in 1861, forming the Confederacy. The Confederacy seized U.S. forts and other federal assets within their borders. Led by Confederate President Jefferson Davis, ...

Davis was a graduate of the U.S. Military Academy, and colonel of a volunteer regiment during the Mexican–American War. He had also been a United States senator from Mississippi and U.S. Secretary of War under President Franklin Pierce. On March 1, 1861, on behalf of the Confederate government, Davis assumed control of the military situation at Charleston, South C ...

32nd Parallel North
The 32nd parallel north is a circle of latitude that is 32 degrees north of the Earth's equatorial plane. It crosses Africa, Asia, the Pacific Ocean, North America and the Atlantic Ocean. In the United States, the parallel defines part of the border between New Mexico and Texas. It was the proposed route of the Texas Pacific Railroad. From 27 August 1992 to 4 September 1996, the parallel defined the limit of the southern no-fly zone in Iraq as part of Operation Southern Watch. This limit was then moved to the 33rd parallel north. At this latitude the sun is visible for 14 hours, 15 minutes during the summer solstice and 10 hours, 3 minutes during the winter solstice.

Colorado River
The Colorado River ( es, Río Colorado) is one of the principal rivers (along with the Rio Grande) in the Southwestern United States and northern Mexico. The river drains an expansive, arid drainage basin, watershed that encompasses parts of seven U.S. states and two Mexican states. The name Colorado derives from the Spanish language for "colored reddish" due to its heavy silt load. Starting in the central Rocky Mountains of Colorado, it 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 Mexico–United States border, 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. Known for its dramatic canyons, whitewater rapids, and eleven National parks of the United States, U.S. National Parks, the Colorado River and its tributaries are a v ...
