Notes
Survey number HAER WY-23-O
Significance: The Clay Spur Bentonite Plant and Camp is associated with the early 20th century bentonite mining industry in Wyoming and the United States. The Clay Spur Bentonite District was the center of the pioneer Wyoming bentonite industry and remained the premier Wyoming producing district until reserves began to dwindle in the 1950s. The plant embodies the distinctive engineering technology of the bentonite industry. The camp also reflects early twentieth century company town architecture with simple buildings and floor plans that could be quickly and cheaply constructed and adapted to many different uses. The refining mill consists of several interconnected buildings, tanks, hoppers, and machinery used in the bentonite refining process. The main line of the Burlington Northern Railroad parallels the southwest elevation of the plant, and a spur line or siding parallels the northeast elevation.
