Timberline was apparently just west of M-33 about 8 mi. north of Rose City and 8 mi. south of Mio on Timberline Mountain. The topo map shows two lift lines running NE/SW to the summit. The satellite shows the slopes and the entrance was south off Co. Rd. 488. An article in the Detroit Free Press on October 27, 1968 lists Timberline as one of four new area (if you include Frontier Mtn.– toboggan only) opening that year. The AAA 1971 Michigan Winter Sports Fun List published on Dec. 10, 1970 in The Cass City Chronicle says Timberline had 6 slopes and 3 rope tows.
