Eastern Washington has hinted several times that they are interested in forming a new state which would include Washington east of the Cascades, and maybe parts of North Idaho and Western Montana, but that has never happened. What has happened was that the very large counties of Eastern Washington were changed over the years to smaller counties. I found an article on the petition to form Wenatchee County in the February 9, 1895 Spokane Chronicle page 1.
Was there ever a Wenatchee County?
What year was this county formed?
