Lake Erie is the fourth largest lake (by surface area) of the five Great Lakes in North America, and the tenth largest globally or twelfth largest globally if measured in terms of surface area. It is the southernmost, shallowest, and smallest by volume of the Great Lakes and therefore also has the shortest average water residence time. Lake Erie's northern shore is bounded by the Canadian province of Ontario, with US states of Ohio, Pennsylvania and New York on its southern and easternmost shores and Michigan on the west. The lake was named by the Erie tribe of Native Americans who lived along its southern shore. There are numerous public parks around the lake. In western Pennsylvania, a wildlife reserve was established in 1991 in Springfield Township for hiking, fishing, cross-country skiing and walking along the beach. In Ontario, Long Point is a peninsula on the northwest shore near Port Rowan that extends 20 miles (32 km) into Lake Erie which is a stopover for birds migrating as well as turtles; one reporter found a "turtle-crossing" sign along the road; Long Point Provincial Park is located there and has been designated as a UNESCO Biosphere reserve. In Ontario's Sand Hill Park, east of Port Burwell, there is a 450-foot (140 m) high dune which is so steep it requires people to "crawl like crabs to the summit" but they are rewarded with spectacular lake views. Crystal Beach, in the Village of Crystal Beach, Ontario, at the Eastern end of the Lake, is one of many South-facing beaches on the Canadian side. As such, it is perfectly situated for sun-lovers and bathers, facing the sun from sunrise to spectacular sunset. The beach is gently sloping with no sharp drop-offs or rip currents, and is usually cooled by southwest breezes, even on the hottest days. In southern Michigan, Sterling State Park offers campgrounds, 1,300 acres (530 ha) for hiking, biking, fishing, boating, with a sand beach for sunbathing, swimming, and picnicking.
