[1] The Au Sable State Forest is a byproduct of the lumbering boom in Michigan during the late 19th century.

Typically, it was sold to subsistence farmers or was reverted to the state in lieu of unpaid property taxes.

In addition, much of the forest is used for wildlife game management and the fostering of rare and endangered species, such as the Kirtland's warbler.

[2] Two land parcels within the Au Sable State Forest are designated as National Natural Landmarks.

The only camping allowed is within Canoe Harbor State Forest Campground, located at the north end of the Tract on the Au Sable River.

The Mason Family constructed the Chapel in 1960 to provide fishermen with a place of reverence and has developed into a popular tourist attraction.
