Upper Sand Island Petroglyphs (SP)

[table “895” not found /]


Special Instructions:

Don Simonis will guide us to an outstanding rock art site with a great time span of thousands of years. See an area on cliffs with over 4,000 petroglyphs. Some petroglyphs are possibly 13,000 to 10,000 years old depicting Mammoth or Mastodon and an extinct form of Bison. Other petroglyphs are from later times made by archaic people, basket makers, ancestral Pueblo, Navajo and Ute. *Bring binoculars.


Meet at Twin Rocks Cafe in Bluff. Directions given at the meeting place.
