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 Cottonwood’s 18.9 sits above most of its state (83% of Minnesota towns have fewer) while its 2 historic buildings outnumber those of 60% of U.S. towns.

Cottonwood county was fortunate in one particular in its settlement in that it did not have to wait long for railroad facilities after the first settlers made their advent. In many localities the pioneer band went into the wilderness ten and twenty years before the sound of the locomotive's shrill whistle was heard there. Hence they had to haul supplies from fifty to one hundred and more miles and also had no market where they could dispose of the stock and crops which they raised, except at faraway cities on some stream or railroad line.
