On a Spirit River Nature Area interpretive sign there are the words:
The Rum River was the super highway for the Isanti Indians. To them, this important waterway was known as Wakpa Wakan,
the Great Spirit River, until a white man's pun turned "spirit" into "rum".
The SPIRIT RIVER NATURE AREA is a two mile long natural area located along side the currently named "Rum" River
in Cambridge, Minnesota.
