What drives La Junta’s History grade

A−
HistoryA character grade: shown, never part of La Junta’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 La Junta’s 23.8 sits above most of its state (81% of Colorado towns have fewer) while its 17 historic buildings outnumber those of 79% 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 (±7.8 points). The founding year is the first post office, not a stated founding date; Wikidata’s 1881 falls in the same era, so the grade doesn’t depend on which one is used.
Founding year: the first post office (other dates in Quick answers). Homes: Census ACS 2020–24.

La Junta (Spanish for 'the junction') was named for the fact it rested at the intersection of the Santa Fe Trail and a pioneer road to Pueblo. The town developed near Bent's Fort, a fur trading post of the 19th century. The Atchison, Topeka and Santa Fe Railway passed through La Junta, with a branch line to Denver separating here.
During World War II, La Junta had an Army Air Force Training Base outside town. An Air Force detachment of the Strategic Air Command remained there until modern flight simulators developed in the 1980s rendered live flight unnecessary for pilot training maneuvers. At least one military aircraft crashed closeby during such training maneuvers.
The La Junta post office opened in 1876, the earliest record of the town by name (U.S. post office records). Wikidata gives 1881.
