Geology of Sacred Sites

Every Sacred Site on earth can be specifically located with its GPS coordinates. The site may be an earth formation or a human creation either placed on the earth surface or some sort of human created inscription on the rock surface. Earth and meaning giving are entwined.

Jeffers Petroglyphs site is an example. It is on the crest of a ridge of sandstone known as Red Rock Ridge. The name given to the rock is Sioux Quartzite. The rock was originally deposited as red sand and mud during the Proterozoic Period. It is sandstone cemented with silicon dioxide and re-crystalized by heat, pressure and chemical solutions.

The site also has wave marks from ancient Proterozoic shorelines nearly 500,000,000 years ago. There are also scratches (striations) from the Des Moines ice lobe of the Wisconsin Glacier some 12 to 14 thousand years ago. The glacial ice was about a mile thick at the time.

The Little Cottonwood River is about 300 yards to the southeast. Remains of a true tall grass prairie are nearby. The site is located 5 miles east and 3 miles north of the town of Jeffers in north-central Cottonwood County of Minnesota, USA.
