From the intersection of State Highway 49 and County Highway Z, just east of Horicon Marsh, go north on County Highway Z 2 miles, then east on Breakneck Road 0.3 mile to the top of the ledge. Southern mesic forest and shaded cliff plant communities are present. Oakfield Ledge features a significant exposure of the Niagara escarpment. The vegetation of the shaded cliff and boulder-strewn steep slope is mostly undisturbed and consists of basswood, sugar maple, red elm, rock elm, red oak, and shagbark hickory. Ground cover includes several patches of Canada yew, walking fern, bulbet fern, fragile fern, cliff brake, and a rare rock cress.
Several springs seep from the cliff face.
The crevices provide excellent habitat for raccoon, woodchuck, cottontail rabbit, and skunk. Its proximity to Horicon Marsh and its natural features make Oakfield Ledge a prime area for migrating birds. Group Use, Research Use, Individual Nature Study, Hunting.
