What drives Sheridan’s History grade

On its age, its old homes and the National Register, Sheridan is more historic than 22% of U.S. towns, #90 of 159 in Colorado. Its age holds the grade up; its National Register listings pull it down.

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 Sheridan’s 0.0 sits below most of its state (22% of Colorado towns have fewer) while its 0 listings outnumber those of 23% 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 is a Census survey estimate (±3.5 points). Two sources give 1890.

The story

How Sheridan came to be

From Wikipedia’s history of Sheridan.

Read it all →

Sheridan was originally part of the Indian Territory and has always been a small community. The first white settler of what would become Sheridan was John McBroom in the spring of 1859. He homesteaded 160 acres (0.65 km2). The town was initially named Petersburg. McBroom built his first log cabin near Bear Creek which he later abandoned in 1866 when he married Emma J. Bennett. He prospered as a farmer and found a viable market in Denver for his goods. He was joined by his brother, Isaac McBroom, in June 1860, who also homesteaded a little over 160 acres (0.65 km2). The laying out of the town of Sheridan is credited to Isaac. He was also responsible for the name change from Petersburg to Sheridan. Isaac McBroom's cabin can be toured at the Littleton Historical Museum.
