Delirium Wilderness
Delirium Wilderness is a wilderness area in Chippewa County, within the Hiawatha National Forest in the U.S. state of Michigan.
The wilderness is forested and flat-to-rolling, with its lower reaches often characterized as a swamp. Elevations range from 590 to 890 feet. Sculpted by glaciers and an ancient glacial lake, it now contains the Sylvester Pond and the Delirium Pond, as well as parts of the headwaters of the Pine and Waiska Rivers.
