If you hike in the desert southwest, you’ll often see Rock Images. Messages from the past that we see in the present.
Though found all over the United States, the dry climate of the Colorado Plateau helps preserves these signs of people who came before us. And stumbling upon art is always amazing.
The generic term is “Rock Images,” but there two common types you’ll see: Pictographs and Petroglyphs
So, what are the differences?
Petroglyphs are carved rock drawings.
Pictographs are paintings found on the rock.
Extremely rare, at least according to a Utah state park brochure are pictoglyphs. Or painted rock carvings. Of course, perhaps most of the pictoglyphs faded with time. Much like Roman statues.
Great! I found some Rock Images! How do I preserve these treasures?
- Obviously, do not deface Rock Images!
- Do not touch! Your oils can damage these ancient artworks.
- And, this part is controversial: But be aware of what you are sharing. The easily accessible and cordoned off Newspaper Rock off a paved Utah highway won’t get impacted by people visiting. A backcountry site that is only reached by an off-trail hike should remain obscure. As I like to say “obscurity, not secrecy.” The folks at Leave No Trace are advocating this line of thought, too. With artifacts centuries old, arguably this type of behavior is the most responsible.
A fun trick that archaeologists use with these, particularly petroglyphs, is to put a negative filter on the picture if the panel is crowded or partially eroded. It can really make some of the design elements pop out that are otherwise obscured. It works especially well in photo editing software where you can use a slider bar to manipulate the values.
Great photos, and thanks for always using your platform to promote preservation of these types of resources!
Thx for sharing. I am familiar with the technique, but don’t like the look for non-academic use. I try to keep my use of filters relatively low.
Just a personal preference! And thx for the kind words!
