John Gregory

John Hamilton Gregory was born around 1820 in Georgia, where he learned placer mining in the diggings of the southern Appalachian gold belt. He joined the westward migration of the late 1850s and was among the thousands drawn to the Pike's Peak country by the reports of 1858.

On May 6, 1859, prospecting up the North Fork of Clear Creek in the mountains west of Denver, Gregory uncovered the outcrop of a gold-bearing vein, the first lode discovery in what became Colorado. The Gregory Lode transformed the faltering Pike's Peak rush into a genuine boom: within weeks thousands of miners crowded into Gregory Gulch, and the camps of Black Hawk, Mountain City, and Central City grew up along it. The district was soon celebrated as 'the richest square mile on earth,' and Horace Greeley himself visited that summer and confirmed the diggings to a skeptical nation.

Gregory sold his original claims for a reported $21,000, worked for a time as a consulting prospector at high fees, and then slipped out of the historical record, reportedly leaving the region in the early 1860s. Accounts of his later life differ: some genealogical sources suggest he died around 1881, but the date and place of his death have never been reliably documented, and his birth year is variously given as about 1820 or 1822. The gulch, the mining district, and a canyon road still carry the name of the man who found Colorado's first lode and then vanished from its history.
