What stands out about Dexter’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
A post office was established in the locality in 1872 and named "Butte Disappointment", after a local landmark named in 1848. The post office was renamed "Dexter" in 1875, apparently after the "Dexter" brand cook stove owned by the postmaster's family.
