Newspaper Rock  petroglyphs.<br />
The first carvings were made around 2,000 years ago, and although a few are as recent as the early 20th century, left by the first modern day explorers of this region, the main groups have been assigned to the Anasazi (AD 1 to 1300), Fremont (AD 700 to 1300) and Navajo (AD 1500 onwards).<br />
The petroglyphs were carved by Native Americans during both the prehistoric and historic periods. 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.
