Geometry in Ages Past

When I saw that this week’s Lens-Artist’s Photography Challenge was geometry, I was at a bit of a loss at first. After all, I do primarily nature photography and although Mother Nature loves a circle or a sphere, she isn’t much into squares and cubes.

Trapezoids, circles and ovals

Then I happened to notice a similarity in the rock art of many of the ancestral peoples of the desert southwest. These folks were really into geometry! Even their sheep were made up of squares and rectangles.

Stylized, geometric depictions of people and animals can be found in rock art from the Fremont culture of northern Colorado and Utah to the Ancestral Puebloans of the Four Corners region to the Mogollon culture of southern New Mexico and Arizona.

Rectangles and squares – These ruins at Gila Cliff Dwellings National Monument in southern New Mexico date back to the 1200s.

Most of the ruins and rock art date back 700 to 1100 years. There are thousands of sites throughout the canyons of the desert southwest, some in quite remote locations. It is so thrilling to walk around a bend in a canyon and discover these traces left behind by people who lived there a thousand years ago!

My first backpacking trip into the desert was in Grand Gulch, Utah. Back then it was just BLM land, in the middle of nowhere. Now it is part of the disputed Bear’s Ears National Monument.  After walking around many bends in the canyon and discovering rock art and ruins here, there and everywhere, I was hooked for life. Searching out Ancestral Puebloan sites on the Colorado Plateau became a hobby and a passion of mine every spring.

The trapezoidal body shape of this petroglyph is typical of Fremont Culture rock art.

By the end of the 1800s, many ruins were damaged and destroyed by pothunters, who would tear up the dwellings in their search for the buried treasure of the artifacts left behind. In 1906 the Antiquities Act was passed by Congress to protect these national treasures.

Petrified Forest National Park
Agate House in Petrified Forest National Park was built out of petrified wood.

Since then, only 5 presidents have not used the Antiquities Act to protect additional lands (Nixon, Ford, Reagan, Bush Sr. and Trump). Trump is the only president who has attempted to remove lands from Monument status.

Many rock art panels have been defaced by bullet holes and graffiti

Theft and vandalism are still major problems faced by those trying to preserve both ruins and rock art. When I worked at Death Valley, we were not allowed to publish any pictures of rock art in the park or disclose locations to visitors because people would literally chip the panels right off the cliffs!

Graffiti and target practice deface many rock art panels. This damage is difficult and often impossible to repair. I can’t help but wonder why some people feel this need to destroy the work left behind by others. I just don’t understand it.

Since enforcement is so difficult, the key may be education. If we can convince others of the value of these ancient artifacts, and how that value is enhanced by being left in place for future generations, perhaps we, and our grandchildren’s grandchildren, may enjoy the geometry of ages past for many more years to come.

  1. A fabulous post, Dianne. Leave it to you to make the connection between ancient cave art and geometry! Now that you’ve pointed it out, it’s so clear that the ancients moved far beyond the circle and straight line into more complex shapes. I’d love to explore some of the ancient sites you mentioned. Like you, I can not fathom why some people want to destroy these relics. (sigh)

  2. An excellent choice of subject for the challenge Dianne – of course you are so right about those who would destroy such amazing treasures. Sadly there is more greed and hate out there than most of us can imagine. One day I would love to visit the cliff homes which are so fascinating – I loved your header image of them especially.

    1. Tina, the header image was Cliff Palace at Mesa Verde National Park, just in case you are wondering for future travel planning.
