History
Formed in 1869 from Lander County
An old deed may name a county that no longer exists, or a boundary that has since moved.
Elko County was created from Lander County in 1869, and gained additional territory from Lander in 1871. In 1877, Elko lost territory to Eureka County, following a failed attempt in 1875 that the Nevada Supreme Court had declared unconstitutional.
