What drives Laporte’s History grade
On its age, its old homes and the National Register, Laporte is more historic than 45% of U.S. towns. Its National Register listings hold the grade up; its share of homes from before 1940 pulls it down.
C+
HistoryA character grade: shown, never part of Laporte’s overall grade.
Few Colorado towns list much on the Register (a typical Colorado town has 1.1 per 10,000 residents, the U.S. 2.4), so Laporte’s 45.2 sits above most of its state (86% of Colorado towns have fewer) while its 8 historic buildings outnumber those of 74% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C− to B. The pre-1940 share (±2.8 points) is firm at this size. The founding year is the first post office, not a stated founding date.

It became the home of Antoine Janis in 1844, who is often noted as the first permanent settler north of the Arkansas River. A band of mountaineers, hunters and trappers made Laporte their headquarters for fur catching and trading operations. The settlement increased in numbers, including 150 lodges of Arapaho Indians who settled peacefully along the river and in the va…
