What drives Chisholm’s History grade

A−
HistoryA character grade: shown, never part of Chisholm’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 Chisholm’s 119 sits above most of its state (98% of Minnesota towns have fewer) while its 56 historic buildings outnumber those of 86% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from B− to A+. The pre-1940 share is a Census survey estimate (±10.7 points). The founding year is the first post office, not a stated founding date.

What stands out about Chisholm’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
The city was named for its founder, Archibald Mark Chisholm (1862–1933), a mining man and investor from Glengarry County, Ontario, Canada. Chisholm was incorporated in 1901. A post office called Chisholm has been in operation since 1901. With a railroad line to Duluth and plenty of mining work available in and near town, Chisholm's population grew rapidly, and by 1908 it had more than 6,000 people and 500 buildings. On September 5, 1908, a fast-moving forest fire obliterated the town due to dry conditions and the wooden construction of nearly all the town's buildings. Many people escaped by going into the lake. No one died in the fire. Afterward, building codes were enhanced, and by the next summer, more than 70 fireproof buildings had been erected.
