History
Weston County was created by the legislature of the Wyoming Territory on March 12, 1890, of land partitioned from Crook County.
Weston County was named for John Weston, a geologist and surveyor. In 1887, Jefferson Weston and Frank Mondell found rich coal deposits north of Newcastle which caused a railroad to be built through the area.
In 1911, Campbell County was formed from portions of Weston County and Crook County. Since then, the boundaries of Weston County have been stable.
