The Au Sable State Forest and Presque Isle State Forest dominate this mid-century landscape, where the sandy highlands of the northern lower peninsula meet a dense network of glacial lakes. In 1950, the area around East Twin Lake and West Twin Lake was a growing hub of seasonal recreation, evidenced by the cluster of lakeside destinations such as Birchwood Beach, Trowbridges Resort, and Birdhaven Resort. These developments represent the post-war boom in Michigan's motor-tourist economy, reachable by the developing County Road 612.
