On March 19, 1903, the Grand County Oil & Refining Company was incorporated in Sulphur Springs, Colorado, with $500,000 in capital stock to pursue regional oil production and refining. This marked one of the earliest independent ventures in the American West, reflecting the rapid expansion of the petroleum industry.
By the early 20th century, Colorado had become home to multiple oil fields producing thousands of barrels per day, helping fuel local economies and the nationwide growth of oil refining infrastructure. The incorporation of Grand County Oil symbolized the shift from small-scale operators to structured industrial enterprises in the West.
