Day 37: November 1, 2004 - Petroglyphs

by Karen Williams
Ancient petroglyphs are scattered throughout Zion National Park, but are not very well publicized to prevent damage. This photograph is from a large group of petroglyphs, which are thought to be carved by Anasazi almost 2000 years ago. The carving also proves that bighorn sheep, which were reintroduced to the park in 1970s, are indigenous to Zion. Petroglyphs differ from pictographs in that petroglyphs are carved, while pictographs are painted.
