Geology
Palisade Head was formed from a

extending from what is now eastern Lake Superior through Duluth to Kansas; this rifting process stopped before an ocean developed. A flow some thick formed extremely hard volcanic rock which resisted a billion years of erosion which cut down surrounding formations.
[ 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.] The feature is a shallow headland, with Lake Superior to the southwest, southeast, and northeast. Its high point is over 300 feet (approximately 90 meters) above the level of the lake; the lakeside cliffs stand up to several hundred feet (60 meters) above water level.

Deaths
Palisade Head is maintained in its natural state, and one can walk right up to the edge of sheer cliffs with the lake directly below.[ In April 2010, a forty-eight-year-old woman fell from the top of Palisade Head and was killed. It is believed that this incident was an accident, because the woman was excited about starting a new job at the time of the fall.]["Hiker dies at Palisade Head"]
Duluth News Tribune, Apr. 10, 2010. On September 11, 2017, a fourteen-year-old girl lost her balance and fell to her death from the top of the cliff.
Human uses
Palisade Head is undeveloped; there are no improvements except for an access road, antenna tower, 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

It is a regional center for rock climbing with many routes up the lakeshore cliffs. The majority of the rock climbing routes range from 5.8 to 5.12 on the Yosemite Decimal System grading scale, with a few routes in the 5.13 range. Most of the climbing routes require traditional climbing gear to protect the climber. A novice climber interested in climbing at Palisade Head may inquire with local gear outfitters that guide outdoor climbing trips.
These cliffs were used for more sinister, albeit fictional purposes in The Good Son, partially filmed on location at Palisade Head.]
