In addition to the federal observance, some U.S. states officially commemorate Leif Erikson Day, particularly in the Upper Midwest, where large numbers of immigrants from the Nordic countries settled. In 1930, Wisconsin became the first state to officially adopt this holiday, thanks to efforts by the Norwegian-American initiator, Rasmus B. Anderson. A year later Minnesota followed suit. In 1963, the U.S. Representative from Duluth, John Blatnik, introduced a bill to observe it nationwide. The following year Congress adopted this unanimously.
In Yukon, Discovery Day is a public holiday commemorating the anniversary of the discovery of gold in 1896, which started the Klondike Gold Rush.
In Newfoundland and Labrador, it commemorates John Cabot's discovery in 1497.
