1989 Map of Greenbush

About this map

Greenbush and the adjacent shoreline of Lake Huron define this late 20th-century landscape on the border of Alcona and Iosco Counties. The settlement pattern is largely shaped by the narrow strip of land between the great lake and Cedar Lake, where a concentration of development includes the Post Office and various public access points. To the west, the topography transitions into the protected timberlands of the Au Sable State Forest, characterized by vast swampy sections and small drainage ways like Van Etten Creek. Evidence of local industry and recreation is visible through several Gravel Pits and a Golf Course located near the northern boundary. The map provides a detailed look at the rural road network, featuring family-named routes such as McGregor Road, Ridley Road, and Dellar Road that connected these coastal communities before further modern expansion.
