Riordan Mansion Evening Lecture: Milton, Arizona: A Conversation About Company Towns
Riordan Mansion State Historic Park
Tuesday, April 28 5:30 p.m. - 6:30 p.m.
Everyone in Flagstaff knows Milton Road, but few know that Milton once was a separate company town owned by the Arizona Lumber & Timber Company. Centered on today's Riordan Road, Milton provided housing and amenities to workers at the Arizona Lumber & Timber Company sawmill, the largest employer in northern Arizona from the 1880s to the 1930s. In this talk, David Portree, guide for Riordan Mansion State Historic Park's Milton walking tours, and NAU history professor Michael Amundson, an expert on company towns, will discuss Milton in its heyday and how it was similar to and different from other company towns in the American West.
Space is limited. Reserve your spot online at https://azstateparks.com/reserve/Activities/Search.aspx or call 928-779-4395 for additional information and same day availability. The presentation will be free thanks to Riordan Action Network.
