Palisade Head cliffs on
Lake Superior, view northeast toward Shovel Point
'Palisade Head' is a large rock formation on the
North Shore of
Lake Superior in the
U.S. state of
Minnesota. It is within
Tettegouche State Park but not contiguous with the rest of that park.
[1] Palisade Head is located at milepost 57 on scenic
Minnesota State Highway 61 approximately 54 miles (86 km) northeast of
Duluth and three miles (five km) east of
Silver Bay.
Geology
''Palisade Head'' is formed from a
rhyolitic lava flow which was extruded some 1.1 billion years ago. During the
Mesoproterozoic era of the
Precambrian eon, the continent spread apart on the
Midcontinent Rift System extending from what is now eastern Lake Superior through Duluth to Kansas; this rifting process stopped before an ocean developed. A flow some 200 feet (60 meters) thick formed extremely hard volanic rock which resisted a billion years of erosion which cut down surrounding formations.
[2] This formed both Palisade Head and Shovel Point, which is within the main part of Tettegouche State Park about two miles (three kilometers) to the east.
[ Minnesota's Geology, , Richard W., Ojakangas, University of Minnesota Press, 1982, ISBN 0-8166-0953-5 ][3] The feature is a shallow
headland, with Lake Superior to the southwest, southeast, and northeast. Its high point is over 300 feet (approximately 100 meters) above the level of the lake; the lakeside cliffs stand up to several hundred feet (60 meters) above water level.

Flora and Fauna
The headland is covered by a mixed forest of
white spruce,
mountain ash,
aspen,
paper birch, and
oak.
[ Palisade Head, Minnesota ][ Fall Color Reports – Palisade Head ] Raptors can often be seen soaring over the cliffs.
Peregrine falcons and
Bald Eagles nest in the area and thousands of
hawks of several species can be seen migrating along the shoreline in the fall.

Human uses
Palisade Head is undeveloped; there are no improvements except for an access road, short-term parking, and a few low rock walls near the edge of the cliffs. On clear days there are views of the
Sawtooth Mountains to the northeast,
Split Rock Lighthouse to the southwest, the
Bayfield Peninsula and
Apostle Islands of
Wisconsin across the lake to the south, and the ship traffic on Lake Superior.
[ It is a regional center for rock climbing with many routes up the lakeshore cliffs.[5] These cliffs were used for more sinister, albeit fictional purposes in The Good Son, partially filmed on location at Palisade Head.[6]]
