B
HistoryA character grade: shown, never part of Crosby’s overall grade.
Minnesota towns list about as much on the Register as the country (a typical Minnesota town has 2.1 per 10,000 residents, the U.S. 2.4), so Crosby’s 31.6 sits above most of its state (90% of Minnesota towns have fewer) while its 7 historic buildings outnumber those of 73% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C+ to A. The pre-1940 share is a Census survey estimate (±5.4 points). The founding year is the first post office, not a stated founding date.

What stands out about Crosby’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Crosby was built for the sole purpose of mining. It was named for George H. Crosby, a businessman in the mining industry.
Crosby was the location of Minnesota's worst mining disaster, the Milford Mine disaster. On February 5, 1924, a new tunnel was blasted too close to nearby Foley Lake, and water rushed in, killing 41 miners.
In the 1932 local elections, Karl Emil Nygard was elected president of Crosby's Village Council, making it the first city in the United States to have a Communist mayor. 27-year-old Nygard won by a vote of 529 - 359, with goals to raise money for families on welfare, declare a moratorium on government debts to local banks, and guarantee water and electricity services to all citizens.
