Map of Wisconsin, highlighting the Door Peninsula.
The 'Door Peninsula' is a
peninsula in eastern
Wisconsin, separating the southern part of the
Bay of Green Bay from
Lake Michigan. The peninsula begins in northern
Brown and
Kewaunee counties and proceeds north to include the bulk of
Door County. It is the western portion of the
Niagara Escarpment. Well known for its
cherry and
apple orchards, the Door Peninsula is a popular tourism destination. With the
1882 completion of the
Sturgeon Bay Ship Canal, the northern half of the peninsula became an island.
Limestone outcroppings, part of the
Niagara Escarpment, are visible on both shores of the peninsula, but are larger and more prominent on the Green Bay side. Progressions of
dunes have created much of the rest of the shoreline, especially on the easterly side.
Flora along the shore provides clear evidence of plant
succession. The middle of the peninsula is mostly flat, cultivated land. Beyond the northern tip of the peninsula are a procession of islands, largest of which is
Washington Island. The partially submerged ridge extends further north, becoming the
Garden Peninsula in
Upper Michigan.
History
Archaeological evidence shows habitation of the peninsula and its islands by several different
Native American groups. Two locations on the peninsula claim to be the landing site of
French explorer
Jean Nicolet in
1634, who was searching for a water route through
North America to
Asia:
Horseshoe Island and Red Banks, which is about 7 miles north of what is now
Green Bay. Nicolet is remembered in Wisconsin lore for having mistaken the
Ho-Chunk Indians for Asians and celebrating, believing he had reached the
Far East.
The name of the peninsula and the county comes from the name of a route between Green Bay and Lake Michigan. Humans, whether Native Americans, early explorers, or American ship captains, have been well aware of the dangerous water passage that lies between the Door Peninsula and
Washington Island, connecting the bay to the rest of Lake Michigan. This small strait, now littered with
shipwrecks, earned the French name ''
Porte des Morts'': in English, "Death's Door".
