Place to see: Newspaper Rock State Historic Monument, Monticello, Utah, United States

About this place:

The Monument features a flat rock with one of the largest known collections of petroglyphs.

The petroglyphs were carved by Native Americans during both the prehistoric and historic periods. Some glyphs depict riders on horses. While precisely dating the rock carvings has been difficult, repatination of surface minerals reveals their relative ages. The reason for the large concentration of the petroglyphs is unclear, making the rock somewhat of a mystery.
