WI 12. The Ridges Sanctuary. Acreage: 700. 



Location: Door County; Sister Bay 15' Quadrangle; at edge of Baileys Harbor. 



Description: A Registered Natural Landmark. Abandoned beach ridges of Lake 

 Michigan, with spruce-fir forest on the ridges and tamarack bogs between them, 

 in long parallel lines. Very unusual habitat conditions have resulted in perhaps 

 the greatest concentration of rare plants to be found anywhere in the Midwest. 

 Especially rich in orchids, heaths, and club-mosses.
