The Cosnino community club was active in the 1910s[6] and 1920s.[7]
A schoolhouse was built in Cosnino in 1924. The Cosnino school was a one-room schoolhouse built one mile from the highway on Walnut Canyon Road, in what the Coconino Sun called "an ideal setting for a rural school".[8] The Cosnino school had an enrollment of 15 in 1926.[9] The school was unusual in that due to heavy snow in the winters, the annual vacation period ran from November to March.[10]
The Cosnino school was also used as a meeting house and was proposed as a location for Sunday school.[11] Community events were also held at the Cosnino schoolhouse.[12] The school in Cosnino was later integrated into the Flagstaff school system.[13]
Cosnino's population in the 1960 Census was 15.[14]
In the 1970s, Cosnino Arena, on Cosnino Road, was the site of 4-H and other agrarian events for area communities.[15][16]
In 1976, proposals were put forward for a new subdivision in the area, called Cosnino Equestrian Estates.[17] The Cosnino Estates area was evacuated in 1988 after a train derailed near Cosnino Road.[18]
