Acadia Ranch, Historic ranch in Oracle, Arizona

Acadia Ranch is a historic complex at 825 E. Mt. Lemmon Highway in Oracle, Arizona, built between 1885 and 1930. Its one-story L-shaped main house combines a five-room adobe core of about 29 by 40 feet with frame, stone, and adobe additions, and has a shed-roofed porch on the north and west sides. A water tower stands southeast of the house, and an outbuilding contains a smokehouse and garage.

Edwin S. Dodge and his wife, who had run a lodging house in Tucson, developed Acadia Ranch in the 1880s with partner Jack Aldwinkle as a lodging house for travelers and summer visitors. One room served as Oracle's U.S. Post Office from 1895 to 1901. A portion of the ranch was listed on the National Register of Historic Places in 1984.

The Oracle Historical Society, a nonprofit founded in 1977, runs the Acadia Ranch Museum in the former ranch house. One room of the building served as Oracle's U.S. Post Office from 1895 to 1901, so the house was both a lodging stop and the town's mail link. The smokehouse, called an ice house, had adobe walls four feet thick.

The museum entrance is on the north side of the L-shaped main house, facing E. Mt. Lemmon Highway; the water tower stands southeast of the house on a small hill. The site lies at 4,500 feet in the Santa Catalina foothills, markedly cooler than Tucson, 35 miles south. The smokehouse walls, once four feet thick, were restored in a project completed in 2013.

The smokehouse, also called the ice house, originally had adobe walls about four feet thick; these eroded over the decades and were restored in a project completed in 2013. The water tower, roughly 12 by 12 feet in plan, stands on a small hill southeast of the main house.
