Mesa Prieta Petroglyph Project Volunteers recently researched and cataloged almost 300 petroglyphs that are on the property at Black Mesa Winery. We happily support Mesa Prieta in their endeavors to preserve local petroglyphs and provide education to the local community about their importance. Our grandson Kristian has participated in their Summer Youth Intern Program for the last two years and has really enjoyed it. We received a detailed summary report of the petroglyphs on the property which includes many wonderful photographs. If you have the time to take a hike while visiting Black Mesa Winery, you might see some of them!
