1920: "Selectmen of the town of Rumford wrote this department during the summer that they would like to have a lookout station established on Zircon Mountain which is located in Milton Plantation.
August 25, 1920: "Deputy Forestry Commissioner Neil L. Violette has returned from a trip to the western part of the State in the interests of the lookout service and reports that it has been decided by the department to erect a steel lookout station on Zircon mountain, which is on the dividing line between Milton Plantation and Peru. It is an elevation of 2240 feet and a station there will cover the greater part not covered by Pleasant mountain station, which is now being erected. This will make five lookout stations in organized towns in the western part of the State and these five will cover all that section. The view from Zircon mountainwill reach to the station on Speckled mountain in Grafton, an unorganized township in the Maine Forestry District. Mr. Violette will probably late in September again visit Zircon mountain to decide on theexact location and what size tower will be needed a 24, 48 or 60-foot steel tower. The actual work of erection will not be done until next year, as it is exceedingly difficult to get any steel work, taking six to seven months to fill an order." (The Lewiston Daily Sun)
