Petroforms are large shapes that were made out of large rocks. Aboriginal groups made shapes of humans, snakes, turtles, and geometric shapes in prehistoric times that still exist intact today.
Some of the shapes might be about 1500 years old. The locations of these can be found in Eastern Manitoba, Canada. Many petroforms have teachings that have been passed down orally by Ojibway First Nations and the Mediwin (Midewewin) Society. Some teachings may have been lost.

These shapes were also used to guide travellers, point out the directions, for astronomical use, and for ceremonial use. They are in need of protection from anyone who might accidentily or purposely move any of these ancient rocks. There are many unknown questions about these fascinating rock shapes that are found in the boreal forests of Manitoba, on flatter, bare surfaces of the Canadian Shield rock ridges. The word "Manitoba" possibly comes from an Ojibway word meaning where the Spirit sits. The location of these petroforms is considered sacred ground by many. One story indicates that this is the area where the first human was put on this Earth. This is the area of some of the oldest rock on Earth, that is mostly composed of pink granite. Other very similar rock circles and medicine wheels can be found across North America. Pink granite is some of the oldest surface rock on Earth that is found in the Canadian Shield. ...
Petroforms are defined as features formed by the placement (not piling) of stones to create the outlines of figures or shapes.
Petroforms, consisting simply of stones placed on bare surfaces, are very susceptible to destruction from natural agents, such as animals or even the weather, as well as people who may inadvertently carry away the stones to build campfires, or who purposefully "rearrange" sites or build "new" ones.
The teachings inherent in the petroforms are considered necessary for the present and future physical, emotional and spiritual well-being of the Anishinabe.
Petroforms, or also known as boulder outlines, or boulder mosaics, are usually prehistoric, human made shapes and patterns that were made by arranging rocks on the open ground.
Petroforms are similar in some ways to medicine wheels which are also aligned with sunrises and sunsets, equinoxes, solstices, lunar events, and star patterns.
Petroforms made upon these granite ridges would have been partially a natural outcome based on the importance and use of the ridges for practical reasons and the abundance of glacial till and boulders to make the petroforms.
