help Jeffers Petroglyphs FAQ
What animals and objects are carved at Jeffers Petroglyphs?
The Sioux quartzite contains images of bison, elk, turtles, thunderbirds, human figures, weapons, and tracks. Atlatls appear among the older motifs, while bows and arrows occur in carvings associated with later periods.
How old are the Jeffers Petroglyphs?
The carvings were not all made at one time, and the Minnesota Historical Society says the site preserves more than 7,000 years of history. Generations of Native people added images to the exposed quartzite over a long sequence of occupation and ceremonial use.
How many carvings can visitors see at Jeffers?
Current Minnesota Historical Society material describes roughly 5,000 inventoried carvings, although older estimates and surveys have used different totals. Many lines are difficult to see because of weathering, lichen, and overlapping images.
When is the best time of day to see the carvings?
The carvings are easiest to distinguish around dawn or dusk, when low-angle sunlight casts shadows into the pecked grooves. Jeffers Petroglyphs also offers guided interpretation because many images are nearly invisible under flat midday light.
