Mobile County, Alabama
Placed 1799
The stone was set by the joint U.S.-Spanish survey party on April 10, 1799. Made of sandstone, it is roughly two feet high and eight inches thick. On the north side of the stone is the inscription "U.S. Lat. 31, 1799." On the south side is "Dominio de S.M. Carlos IV, Lat. 31, 1799."
Ellicott's Stone is one of the most important early boundary markers in the history of the Americas, demarking the boundary between Spanish and U.S. territory. The location of Ellicott's Stone was the result of the 1795 Pinckney Treaty (formally called the Treaty of San Lorenzo) between Spain and the U.S. In it, both countries agreed that 31 degrees north latitude-about midway up Alabama-would be the east-west boundary between U.S. Mississippi Territory and Spanish West Florida.
Sir William Dunbar performed the survey east of the Mississippi on behalf of Spain. Major Andrew Ellicott was appointed by fellow surveyor, President George Washington to establish the international boundary starting at the Mobile River and working toward the Atlantic.
The historic stone marker was placed in 1799 near the bank of the Mobile River where the 31st parallel was considered to be. The parallel remained the boundary for only 14 years, until America obtained Mobile from the Spaniards in 1813.
Facts
- The Pinckney Treaty included provisions that the boundary would be surveyed and marked to end further disputes. Spain, however, was disappointed to find that both Natchez and the then-thriving community of St. Stephens, Alabamas early capitol, would be on the U.S. side. Spain consequently conducted political maneuvering to delay the survey. Work was held up for three years; but in 1798, the U.S. insisted that the surveying begin.
- Ellicott and his survey crew encountered many obstacles, including rough terrain, dissident laborers, nearly impenetrable swamps, and Indian attacks. Using homemade surveying instruments and the stars for guidance, he was able to place the stone just 500 feet south of the true 31st parallel.
- This survey established the basis for many later surveys including the St. Stephens Meridian and the St. Stevens Baseline.

Paterson, New Jersey
Constructed 1792-1864
"In Paterson people did not just invent; they tried everything - a repeating revolver, a submarine, an airplane that could fly across the Atlantic. And Paterson did not just manufacture; it produced articles that redefined the limits of life."
- Christopher Norwood, "About Paterson", Saturday Review Press, 1974
Visionary Alexander Hamilton, the United States' first Secretary of the Treasury, visited the Great Falls of the Passaic River with George Washington in 1778. The 77-foot-high, 280-foot-wide waterfall inspired his dream of abundant, inexpensive energy as the means for economic independence from foreign markets.
In 1791 Hamilton enlisted the aid of some patriots, industrialists, and financiers to form the "Society for Establishing Usefull (sic) Manufactures" (S.U.M.) specifically to create America's first industrial community. The S.U.M. then hired Pierre Charles l'Enfant and Peter Colt to design and oversee construction of the first raceway and power system in Paterson to harness the Passaic River's energy.
The energy provided by the Great Falls raceway and water power system fostered countless engineering and industrial innovations, including the Colt revolver, the Holland submarine, the Curtiss-Wright aircraft engine, and textile and silk manufacturing which made Paterson famous as the "Silk City."
Facts
- The Society for Establishing Usefull [sic] Manufactures operated the early raceway system from 1794 to 1799 and diverted water from the Passaic behind a wooden dam above the falls. The water then entered into a reservoir and passed through the raceway to a flume and waterwheel to provide power for operating a mill.
- The raceway and power system was modified several times in the 1800's as the use of water power for manufacturing evolved from a simple waterwheel to hydroelectric power.
- The system today represents one of the finest and most extensive remaining collections of engineering, planning, and architectural works of the period of the United States' earliest industrial development.

I tried to frame this one to achieve a Kubrickesque monolith feel.
