HistoryA character grade: shown, never part of Palmer Lake’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 Palmer Lake’s 7.6 sits above most of its state (68% of Colorado towns have fewer) while its 2 historic buildings 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 (±6.1 points). Two sources give 1871.

The earliest known area inhabitants were Native American tribes - the Mountain Ute, Arapahoe, Kiowa, and Cheyenne. The earliest recorded non-Native activity in the area was the Army's Major Stephen Long Expedition of 1820, which discovered the Colorado State Flower, the white and lavender columbine, somewhere between Monument and Palmer Lake. Many homesteaded ranches and farms straddled the El Paso-Douglas County line as early as the 1860s. David McShane is credited with being one of the first homesteaders, 1865, in the Town of Monument. Henry Limbach and his family were also early arrivals and had much to do with planning and developing of Monument which prospered as the commercial hub for the area on arrival of the railroad.
