Our classroom is the 489 acre Arkansas Natural Heritage Commission Bear Hollow Natural Area. The area features nearly eight miles of trails, bluff shelters, rock outcroppings, glades, a historic farmhouse and cabin, and beautiful vistas. Students also learn about water quality and conservation during lessons in and along the crystal clear waters of Bear Hollow Creek, which bisects the natural area. ONSC is also adjacent to the approximately 15,000 acre Arkansas Game and Fish Commission McIlroy-Madison County Wildlife Management Area. Our studies often take us to this adjacent public property to study forest and cave ecology and to experience several waterfalls and creeks.
