Delirium is bounded on the north by Forest Roads 3130 and 3352 and on the south by Forest Road 3131. The Lake Superior State Forest borders the area on the east. Three miles to the north is State Highway M-28 at Raco. The Delirium area is administered as a part of the Sault Ste. Marie Ranger District of the Hiawatha National Forest.
Human influence is apparent in the area.
Past strip cutting of cedar trees is evident in some areas of swamps. Old stumps and former roadways from early 1900's logging are also apparent. The Sylvester Dam and its access are situated within the heart of the wilderness, geographically, yet are excluded from it by the designated boundary. The earthen dam was installed about 18 years ago and is natural appearing, as is the 80-acre pond. The landscape which was formed from old glacial lakes is flat to rolling with elevations ranging from 590 to 890 feet.
