Delirium Wilderness
Located in the Hiawatha National Forest in Michigan.
The Delirium Wilderness is located in Chippewa County, Michigan. It lies 22 air miles southwest of Sault
Ste. Marie. The village of Rudyard lies 3 miles to the southeast. 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. Two water bodies are found in the area; 80-acre Sylvester Pond and the six-acre Delirium
Pond. Overall character of the land can be described as swamp.
As the headwaters for the Pine and Waiska Rivers, these wetlands serve to help recharge the aquifer, filter
and retain nutrients and sediments (purify the headwaters), and provide habitat for waterfowl and
furbearing wildlife species. Tree species within the area include swamp conifers, aspen and white cedar
in the wetlands and red pine and jack pine in drier areas.
Wildlife predominant in the area includes: beaver, bobcat, otter, ducks, loons, great blue heron and some
sandhill cranes. Whitetail deer, black bear and rabbits are also common species found in the area. To
protect nesting areas of waterfowl species visitors are discouraged from using Delirium in the spring and
early summer.
Current recreation use is primarily hunting and trapping. The thickly forested swamps, surface water and
biting insects limit other forms of recreation. For those willing to face these challenges the area's vast
acreage enhances the potential for experiencing a feeling of solitude. In wintertime, visitors may discover
a greater ease of travel freedom from insects and quiet. The Delirium area may also appeal to the person
who appreciates and wishes to study plants and animals associated with wetland types.
There are no marked pathways in the Delirium Wilderness. Expert orientation skills are needed to find
one's way into and out of the area. To fully experience the wilderness value of the area a visitor should
have a genuine interest in the study of wetlands and the ability to endure some physical discomfort.
