Delirium Wilderness is a {{convert|11870|acre|km2|1|adj=on}} wilderness area in Chippewa County, within the Hiawatha National Forest in the U.S. state of Michigan.[http://www.fs.fed.us/r9/forests/hiawatha/recreation/wilderness/delirium/index.php Delirium Wilderness] - Hiawatha National Forest[http://www.wilderness.net/index.cfm?fuse=NWPS&sec=wildView&WID=152 Delirium Wilderness] - Wilderness.net

The wilderness is forested and flat-to-rolling, with its lower reaches often characterized as a swamp. Elevations range from 590 to 890 feet (180 to 270 m). Sculpted by glaciers and an ancient glacial lake, it now contains the {{convert|80|acre|ha|0|adj=on}} Sylvester Pond and the {{convert|6|acre|ha|0|adj=on}} Delirium Pond, as well as parts of the headwaters of the Pine and Waiska Rivers.
