What drives Crystal Lake’s History grade
On its age, its old homes and the National Register, Crystal Lake is more historic than 39% of U.S. towns, #473 of 768 in Illinois. Its National Register listings hold the grade up; its share of homes from before 1940 pulls it down.

HistoryA character grade: shown, never part of Crystal Lake’s overall grade.
Few Illinois towns list much on the Register (a typical Illinois town has 0.5 per 10,000 residents, the U.S. 2.4), so Crystal Lake’s 0.5 sits near the middle of its state (60% of Illinois towns have fewer) while its 2 listings outnumber those of 60% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C to C+. The pre-1940 share (±0.9 points) is firm at this size. The founding year is the first post office, not a stated founding date; Wikidata gives 1914.

The City of Crystal Lake traces its origins to two communities established in the 1800s. Those communities were generally known as Nunda and Crystal Lake. In 1835, Ziba S. Beardsley came to the shores of the lake and commented that the "waters were as clear as crystal", thereby giving the lake its name. Ziba Beardsley continued south to Naperville. In February 1836, the first white settlers, Beman and Polly Crandall, and six of their ten children arrived from New York State, traveling to Crystal Lake in a covered wagon. Their original cabin was built near today's intersection of Virginia Street and Van Buren Street. Four of the Crandall children were born there. Najah Beardsley's family was the second to settle in the area; his grandson, William Beardsley, was the first white child born on the Crystal Lake prairie, on May 7, 1837.
