 Fremont County is roughly the size of Vermont with an area of over 9,200 square miles. It was once much larger, but several counties were carved out of the original area. Fremont County consists of the Wind River Valley with the Wind River Mountains to the south and west and the Outcreek Mountains to the north. Before Wyoming was even a state, the Shoshone Reservation was established for the eastern Shoshone Indians. They moved into the area only after a military outpost was built, which is now Fort Washakie. A few years later, the Arapaho tribe was moved to the reservation, now called the Wind River Reservation. The first oil well in Wyoming was drilled east of Lander. Fremont County has gone through numerous boom and bust cycles, leaving abandoned and reshaped towns. Gold brought the first influx of people to South Pass City. Coal mining near Hudson caused the swell and shrink of this little town. Railroad ties brought a temporary economic boom to Dubois and Riverton. The nearly abandoned Jeffrey City once had 4,000 residents from the uranium mine. Finally, Atlantic City residents mined iron ore as late as 1983. Agriculture is a major contributor to the county's economy. Fremont County ranks number one in Hay and Alpha Alpha production and has the third highest cattle numbers in Wyoming. As you drive through, stop and take the time to enjoy the culture, beauty and history that Fremont County has to offer.
