Did you know...

Mills was established in 1921 as a sand and gravel community in support of the oil fields and refineries in the nearby towns of Casper and Midwest. During the late 1800’s and early 1900’s, workers hauled string teams—teams of 12 to 18 horses or mules pulling a train, or string, of several wagons holding tanks of oil to and from the Salt Creek Oil Field, beginning 20 miles north of Mills. The refining of oil required vast quantities of water only available locally at the North Platte River. As the refining expanded, there was a need for sand and gravel to use in construction of the tank farms and roadways. The Mills Construction Company, located in Mills, had the major contract to supply sand and gravel to the refinery for this construction. As Mills grew in population, over 500 residents decided there was a need for local government and thus formed present day Mills, WY; now inhabited with over 4,000 residents and a multitude of diverse businesses.
