wyoming cattle industry

Seth Ward and William Guerrier built Sand Point Post at Register Cliff, the first stop west of Fort Laramie, where they pioneered livestock exchange and open-range wintering that launched Wyoming’s cattle industry. It operated for sixteen years, doubling as mail and Pony Express station.

After the Grattan Fight forced Platte River traders to Fort Laramie in 1855, Seth Ward and William Guerrier built a trading post just across the river. Ward became the fort’s sutler in 1857, anchoring one of the corridor’s most successful trading partnerships until 1863.
