Riordan was located on the Atchison, Topeka and Santa Fe Railway (AT&SF) approximately 6.5 miles (10.5 km) west of Flagstaff, Arizona.[3] It was near the Arizona Divide.[4]
Brothers Michael and Timothy Riordan from Chicago established the Riordan Lumber Mill; the town of Riordan grew up around the Riordan Mill and was named in 1897.[3] Riordan was named in honor of D.A. Riordan.[5]
A second sawmill, owned by the Coconino Lumber Company, opened in Riordan in 1912.[6] In June 1916, ownership of the Riordan mill passed to brothers Charles and Edward McGonigle.[3] The name of the mill company was changed to the McGonigle Lumber Company, with its main offices in Riordan.[7]
The Santa Fe Railway constructed a depot, bunkhouse, and several dwellings; the logging company established a store. The post office in Riordan was established in June 1917.[3] At that time, the Flagstaff Coconino Sun stated that "Riordan is rapidly growing into a thriving little city".[7]
The Church of the Nativity, a Catholic church in Flagstaff, operated a station in Riordan circa 1920.[8]
The Riordan School operated briefly in the 1910s and 1920s.[9][10] Originally, the Riordan School was in a rented building, but in 1913, Coconino County announced provisional plans to construct a new school building.[11]
The McGonigle mill closed in June 1924 due to a slump in the lumber industry. The Riordan post office followed in September 1925.[3] Riordan's population was 16 in 1925.[12]
There were discussions in 1924 about closing the Riordan School, with local children going to school in Flagstaff.[13] In 1926, the Riordan School District (#16) had one clerk and a single teacher, who taught first through eighth grade.[14] The Riordan schoolhouse was sold that year.[15]
In 1934, there was a major forest fire near Riordan.[16] In June 1934, more than 500 acres of the Coconino National Forest burned before the blaze could be brought under control.[17]
