Description

Description

Four of the 21 islands in Lake Superior’s Apostle Islands archipelago comprise this State Natural Area. The Apostle Islands Sandscapes SNA was established in 1992 to recognize and protect a variety of unique sand-based landforms, including dunes, beaches, sand spits, cuspate forelands, and tombolos. Sand spits are long, narrow sand deposits extending outward into the water from a tip of land or at the mouth of a bay. Cuspate forelands are similar to sand spits but are wider and wedge-shaped. Sand deposits that connect an island to the mainland or connect two islands are called tombolos. Stockton Island contains the largest (622 acres) and most diverse unit of the sandscape natural area. The southeastern tip of the island, Presque Isle Point, was once a separate island. After the glaciers receded, shore currents deposited ridges of sand forming a sand bridge, or tombolo, between Presque Isle and Stockton Island. The tombolo, the only one in Wisconsin, consists of dry, sandy ridges, low dunes and a wide beach. The ridges feature an excellent red pine barrens. The east side of the tombolo contains open wetlands with bog, sedge meadow, and emergent aquatic vegetation. Several rare plants are found here, including three state-threatened species: Michaux’s sedge (Carex michauxiana), lenticular sedge (Carex lenticularis), and English sundew (Drosera anglica). The southernmost point of Outer Island features a 1½-mile long sand spit and associated beach and low dunes. Beach grass, wormwood, creeping juniper, and beach pea are among the plant species stabilizing the sand. The spit encloses a large lagoon with shrubby margins that grades to a rich, open bog dominated by sedges, rushes, and ericads. The interior of the point supports semi-open dry forest of red, white, and jack pines with a blueberry-sweet fern understory. Migratory birds make extensive use of this 232-acre natural area in spring and fall. The 22-acre Rocky Island unit contains a small cuspate foreland on the island’s southeast tip. An open, boggy wetland is included within the natural area boundary. The southeast side of Raspberry Island is dominated by a sand spit and associated dunes and beach. The 6-acre sandscape encloses a small sphagnum bog.

Maps

The WDNR'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. Therefore, while the majority of SNAs are open to the public, access may vary accordingly. 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 land owner 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.

Activities

Please come prepared for your visit. Amenities vary from site to site with most SNAs being primitive and without facilities. See Guidelines for Visitation for details.

Allowable Activities

Most DNR-owned SNAs allow:

• Hiking
• Hunting
• Fishing
• Trapping
• Skiing

Some exceptions apply. Properties closed to the public or closed to specific use, such as hunting, will be posted.

***For non-DNR-owned SNAs: Additional use guidelines may apply. Please verify any use restrictions with the landowner or contact the SNA Program. Landowners may require additional permits or restrict the number of hunters at a given SNA to provide a quality hunting experience. SNA landowners can be found at the bottom of each SNA description page.

Prohibited Activities

• Horseback riding
• Rock climbing
• Vehicles, including bicycles, ATVs, aircraft, and snowmobiles except on trails and roadways designated for their use
• Collecting of plants (including fruits, nuts, or edible plant parts), animals, fungi, rocks, minerals, fossils, archaeological artifacts, soil, downed wood, or any other natural material, alive or dead

Please note that a permit is required for scientific collection and research on State Natural Areas. For more information, contact Thomas Meyer, State Natural Areas Program Specialist.
