At the confluence of Ralston and Clear Creeks, the explorers indeed found gold, but not enough to make much of a profit, even with the addition of sluice boxes powered by canals. They began to move upstream, in the hope of finding richer deposits, perhaps even veins of gold. And so they did, at Gregory Gulch, with the famous find that started the Gold Rush of 1859. Too bad Ralston went back to Georgia just in time to miss the bonanza. However, the canals they dug proved to be extremely valuable to the real future of Arvada, farming. By 1870, the Colorado Central railroad had reached this far West, and enough people had moved into the area, that an official U.S. Post Office was requested. The leading citizen, Benjamin Franklin Wadsworth, asked his wife Mary Ann to name their new community. Her sister had married a man named Hiram Haskin. Hiram's mother had chosen his middle name off a map in their old Scofield Bible, and so Arvada was born, named for an island off the coast of Syria. Wadsworth and his friend Louis Reno platted the town in 1870, marking its first existence in an organized fashion. Population at that time was about 100 people. Arvada was officially incorporated in 1904, and today boasts over a hundred thousand residents.
