HistoryA character grade: shown, never part of Lolo’s overall grade.
Montana towns list more on the Register than most of the country (a typical Montana town has 12.7 per 10,000 residents, the U.S. 2.4), so Lolo’s 2.3 sits near the middle of its state (39% of Montana towns have fewer) while its 1 listings outnumber those of 51% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from D to C. The pre-1940 share (±0.6 points) is firm at this size. The founding year is the first post office, not a stated founding date.

What stands out about Lolo’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
The Traveler's Rest site, in Lolo, is one of the few sites in the nation with physical confirmation of the visit of Lewis and Clark.
There are several versions of the origin of the town name. One is a French pronunciation of the name Lawrence Rence, a fur trapper in the area. Another is the French name for Meriwether Lewis, "Le Louis". Or it could be based on either a Chinook word or a Nez Perce word. In addition to the town, a national forest, creek, mountain peak, mountain pass, hot springs, and historic trail are all named Lolo.
The 2017 Lolo Peak Fire burned thousands of acres 10 miles (16 km) southwest of Lolo, prompting evacuations and closure of U.S. Route 12.
