Mailboxes (Knoke, Iowa)

Mailboxes (Knoke, Iowa)

These eight mailboxes represent the remaining households and businesses in the unincorporated community of Knoke, located in the northwest corner of Calhoun County, Iowa. Knoke was home to a full-time post office through 1963, when it was shuttered in favor of a locally-operated contract branch office; that office operated 25 years before it was discontinued. Knoke is now part of a rural route originating in the nearby community of Fonda.

At first glance, visitors may believe the post office in Rubio is still active: the yard is well-maintained, United States Postal Service logos can be found on both windows, and the official zip code sign is still in place on the south side of the building.┬áIn reality, the Postal Service hasn’t operated in this Washington County community since June 1980. The unincorporated community of Rubio lost its zip code and residents now receive mail via nearby Richland’s rural route.
