History

Formed in 1853 from La Crosse County

An old deed may name a county that no longer exists, or a boundary that has since moved.

Jackson County was created from La Crosse County on March 1, 1853, though it was initially not fully organized and remained attached to La Crosse for judicial purposes. Jackson was fully organized and detached from La Crosse on September 1, 1853, and over the following years experienced multiple boundary changes: it lost territory to the creation of Buffalo and Clark counties, lost and gained land from Chippewa and Clark counties, lost territory to La Crosse and Monroe counties, and exchanged land with Wood County.
