Paul Bunyan Day is named after the giant lumberjack in American folklore and is observed on June 28. 2022. Paul Bunyan was accompanied by a blue ox named Babe, and it is said they were so huge, that their footprints created the many lakes of Minnesota. Especially Lake Bemidji reminds one of a big footprint when you look out of a bird's eye perspective on it.
The earliest published versions of the myth of Paul Bunyan can be traced back to James MacGillivray, a traveling newspaper reporter who wrote the first article about Bunyan for Oscoda Press in 1906.
