Beaver Creek Rock Art - Petroglyphs, V-bar-V, Verde Valley, Arizona, USA by N3074Echo Via Flickr: The V-bar-V petroglyph site is the largest known rock art site in the Verde Valley of central Arizona, and one of the best-preserved. This site consists of 1,032 petroglyphs in 13 panels. Acquired by the Coconino National Forest in 1994, the site is protected and kept open to the public by the US Forest Service. Opening times are Friday, Saturday, Sunday and Monday. The petroglyphs were created by Southern Sinagua residents between a period from 1150 and 1400 AD. The site was known to early American settlers, and became part of the historic V-bar-V ranch around 1907. The ranch headquarters were nearby, and the ranchers protected the site from vandalism. Some historic ranch buildings remain near the Visitor Center.
