What drives Limon’s History grade
On its age, its old homes and the National Register, Limon is more historic than 47% of U.S. towns. Its National Register listings hold the grade up; its age pulls it down.
B−
HistoryA character grade: shown, never part of Limon’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 Limon’s 11.9 sits above most of its state (74% of Colorado 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 B+. The pre-1940 share is a Census survey estimate (±9.8 points). The founding year is the first post office, not a stated founding date.

What stands out about Limon’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Railroads were the major factor for Limon's original founding and location. The Kansas Pacific Railroad made its way across the plains from southern Kansas following the Smoky Hill Trail in 1870. In 1888, the Chicago, Rock Island, and Pacific Railroad (now the Kyle Railroad) made its way west to east from Colorado Springs, entering Lincoln County and intersecting the Kansas Pacific (now Union Pacific) at the present day location of Limon. This union of the two railroads was the earliest founding of the "Hub City".
Fire insurance maps drew every building, what it was made of and what it was used for, so insurers could price the risk of fire. Pick a year, then a sheet.
