In 1880, a grain miller named Gabriel Bowen filed a claim to an oil spring on the east bank of Four Mile Creek. Within two years, A.M. Cassidy and his partners had acquired the oil spring and drilled a well- the first oil well in Colorado. Wagons hauled the oil to Denver, Pueblo and Santa Fe to be used as lamp oil and machine lubricant. Eventually, this small oil well led to the discovery of the Florence Oil Field in 1881.
