Project aims to preserve an Arizona tribe's cultural history

Hidden away in Christmas Tree Pass near the Arizona-Nevada border, more than 700 petroglyphs can be found at Grapevine Canyon.

The petroglyphs, which were carved into the canyon rocks sometime between 1100 and 1900 AD, are a reminder that the history of the Colorado River extends long before Davis Dam made its mark on the landscape. The Pipa Aha Macav, or “The People By the River,” once occupied lands stretching from Utah to Mexico, and east to west from modern-day Santa Barbara to Prescott.Now known as the Fort Mojave Indian Tribe, the group’s land was reduced by settlers and now stretches from Mojave City to Topock, and straddles the Nevada, California and Arizona borders.
