Until you can schedule a trip to the Santa Fe/Espanola area to see the Mesa Prieta petroglyphs for yourself, please enjoy a virtual tour courtesy of the Archaeological Conservancy's Virtual Tour Series. To date the Archaeological Conservancy has released four episodes showcasing some of the sites they have acquired for preservation and protection. They are all worth your time.
Scroll down at this link to check out Episodes 1 through 3, but Episode 4 is the one that is all about petroglyphs the like you have never seen before. It features their Wells Petroglyph Preserve narrated by their archaeologist, Chester Liwosz, and former owner/donor/founder of the Mesa Prieta Petroglyph Project, Katherine Wells. If time permits you can watch the full hour-long virtual tour here, or see the same episode in four shorter segments by clicking here.
Of course, the Archaeological Conservancy also has an ongoing Virtual Lecture Series to keep you apprised of the latest in research. Get busy!
