No. 648

Located in the hilly western upland region of Rock County, Magnolia Bluff marks the second highest point and the only relatively undisturbed cliff in the county. Comprised of Galena dolomite and St. Peter sandstone, the bluff, including its narrow ridgetop, has been deeply incised by natural drainage ways with open and shaded cliffs flanking the sides. Southern dry-mesic forest dominated by black oak covers most of the area with white oak, bur oak, shagbark hickory, and American elm. Paper birch, found at only a handful of locations in the county, is locally abundant on the north-facing slopes.

The cliffs and dry, open slopes above support several plant species including ebony spleenwort, smooth cliffbrake, rusty woodsia, spike-moss, common rockrose, bird's-foot violet, huckleberry, and small skullcap. A state-threatened species is also present here. On the crest and upper slope of the bluff is a small dry prairie remnant with little bluestem, side oats grama grass, rock sandwort, and blue-eyed grass. Magnolia Bluff is owned by Rock County and was designated a State Natural Area in 2011.

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. If a developed trail is present, it will normally be noted on the SNA map and/or under the Maps tab. A compass, topographic map, or GPS unit are useful tools for exploring larger, isolated SNAs.

The good majority of SNAs are isolated and have few or no facilities. Some SNAs have vehicle access lanes or parking lots, but their accessibility may vary depending on weather conditions. Parking lots and lanes are not plowed during winter. Hiking trails may be nonexistent or consist of undeveloped footpaths. A GPS unit or compass and a detailed topographic map are valuable tools for exploring larger SNAs.
