No, actually, it's not. the "Wild West" as shown in the movies and TV is basically 1870-1920 in the Southwest (NM, AZ, NV, CO, UT, eastern CA) and 1895 or so in the PNW (OR, WA, ID, Western CA.)
Seattle was "Civilized" by 1900. By 1926 the highways basically connected coast to coast, and the west was done.
1912 was the end of the territories in the (now) contiguous 48 states, with the joint admissions of AZ and NM
Many historians argue the "Wild West" period to be 1870 to 1890. A few argue for 1880-1890. Others give it as 1860-1920.Pretty much any way you cut it, 1889 is still in the Wild West, and the Challenge Article on the West in 1889 is pretty clearly thinking "Wild Wild West" and "Wild West", not Civilized Oregon (Many look at Washington State's admission as the end of the Wild West, and that's 1889).
Alaska and Hawai'i both had territorial police by 1920, and neither had the "western" mentality.
