Wisconsin State Natural Areas Program Johnson Hill Kame (No. 258)
Within Kettle Moraine State Forest Northern Unit, Sheboygan County. T14N-R20E, Section 8. 11 acres.
Johnson Hill Kame is a "moulin" kame, a conical hill of sand and gravel formed near the edge of the wasting glacial ice sheet by subglacial meltwater streams that poured downward through cylindrical holes in the glacier. The swirling motion of the debris-laden water reminded early French mountaineers of a moulin (mill in French). Hundreds of spectacular glacial features can be found within the Kettle Moraine and the Northern Unit contains one of the best displays of moulin kames in the country. Surrounding the kame is both southern and northern dry-mesic forest. The southern slope is composed of red oak, big-tooth aspen, beech, ironwood, sugar maple, butternut hickory, basswood, white oak, and eastern hop-hornbeam. The cooler north slope consists of basswood and sugar maple with beech, red oak, and eastern hop-hornbeam. Johnson Hill Kame is owned by the DNR and was designated a State Natural Area in 1992.
From the intersection of State Highways 67 and 23 in Plymouth, go south and west on 67 8.7 miles, then south on County U 0.1 mile, then continue south and east on Woodside Road 0.75 mile, then south on Shamrock Road 0.4 mile. Park along the road and walk across the field to the kame.
Johnson Hill Kame is owned by:
The DNR's state natural areas program is comprised of lands owned by the state, private conservation organizations, municipalities, other governmental agencies, educational institutions and private individuals. While the majority of SNAs are open to the public, access may vary according to individual ownership policies. Public use restrictions may apply due to public safety, or to protect endangered or threatened species or unique natural features. Lands may be temporarily closed due to specific management activities. Users are encouraged to contact the landowner for more specific details.
The data shown on these maps have been obtained from various sources, and are of varying age, reliability, and resolution. The data may contain errors or omissions and should not be interpreted as a legal representation of legal ownership boundaries.
Manage the site as a geologically significant forested Moulin kame. The geological feature is the primary purpose for protection and management. Another objective is to provide opportunities for research and education on the highest quality glacial kames.
The native forest species are managed passively, which allows nature to determine the ecological characteristics of the site. Exceptions include control of invasive plants and animals, and access to suppress fires. Salvage of trees after a major wind event is not considered compatible with management objectives.
- A former tube run on the north slope is abandoned and will gradually succeed to an old forest.
Very few State Natural Areas have public facilities, but nearly all are open for a variety of recreational activities as indicated below. Generally, there are no picnic areas, restrooms, or other developments. Parking lots or designated parking areas are noted on individual SNA pages and maps. Trails, if present, are typically undesignated footpaths. If a developed trail is present, it will normally be noted on the SNA map and/or under the "Access" tab. A compass and topographic map or a GPS unit are useful tools for exploring larger, isolated SNAs.
In general, the activities listed below are allowed on all DNR-owned SNA lands. Exceptions to this list of public uses, such as SNAs closed to hunting, are noted under the "Access" tab above and posted with signs on site.
- Cross country skiing
- Horseback riding
- Rock climbing
- Vehicles, including bicycles, ATVs, aircraft, and snowmobiles except on trails and roadways designated for their use
- Collecting of animals (other than legally harvested species), non-edible fungi, rocks, minerals, fossils, archaeological artifacts, soil, downed wood, or any other natural material, alive or dead. Collecting for scientific research requires a permit issued by the DNR
- Collecting of plants including seeds, roots or other non-edible parts of herbaceous plants such as wildflowers or grasses
- Camping and campfires
