Big Piney and Marbleton, Wyoming
White settlement in Sublette County, Wyo. traces its roots to the late 1870s, when cattlemen brought herds to the pastures where North, Middle and Piney Creeks join the Green River. The town of Big Piney was incorporated there in 1913. The next year, neighboring Marbleton was incorporated a mile away, on higher ground on the bench above Piney Creek. Every effort to combine the two towns has failed, and they continue to maintain separate governments though they share most other services. The energy industry is now the major employer in both communities. Big Piney registered a population of 552 in the 2010 census, and Marbleton, 1,094.
