Petroglyphs: The Writing on the Wall

Petroglyphs are images scratched into rocks using other rocks or instruments. In the desert, rocks often gather a dark patina that can be chipped away to reveal a lighter surface underneath. These are ideal surfaces for creating petroglyphs.

These drawings are found in many locations around the world. and those created by ancient peoples tend to hold a certain mystique.

NOTE: – Paintings on rocks are referred to as pictographs or petrographs.

Some Petroglyphs are relatively recent, perhaps as young as the early twentieth century while others are tens of thousands of years old.

During our many hikes across the United States, we have seen a number of established petroglyph sites.

One of the most interesting encounters was Newspaper Rock State Historic Monument in Utah which can be found along the main road leading into the Needles section of Canyonlands National Park.



The photo above was of the left-hand side of the main display. A number of the images are self-explanatory while others remain mysterious. These are estimated to be 2,000 years old according to the park’s website.



This lighter section was a less “populated” area even farther left of the area shown above. It is amazing how well the petroglyphs have stood the rigors of weather over time. Notice that some drawings such as the feet and the quartered circle are repeated in a number of areas shown in the photographs.



The last section, located on the right-hand side of the monument, is carved on very dark rock. A variety of animals and hunters can clearly be seen.

What I find almost equally astounding is that these images do not seem to have been defaced. There is only a short fence blocking off this ancient canvas which could easily be breeched. Kudos to the thousands of visitors who have admired this precious view into the past and have kept it safe for others to witness.

Valley of Fire State Park, Nevada

We were fortunate enough to have time to visit petroglyphs at the Valley of Fire State Park. Although these were not at ground level, a scaffolding was erected to enable easy viewing of the ancient artistry.

A number of the images were similar to those at other sites.


 


 

Unfortunately there was some alteration, or more accurately, violation of these ancient treasures, shown in the picture below via the circle.


 

The names Herman and Janine were carved into the face of the large rock.


Painted Desert – Another Rock, Another Newspaper

The Painted Desert also has a Newspaper Rock although it is not as easy to “read” as the Canyonland’s Edition.

The artifacts can be viewed from a fenced-off, elevated area just a short walk from the large parking lot. Don’t expect to get a good picture of the actual drawings unless you have a camera with a fairly large telephoto lens.

This is what you will see from the viewpoint above the rock formation. I have placed yellow arrows where the petroglyphs are located. On a sunny day, there is shade covering much of the surface (obviously depending on the the time of the day) making them difficult to see with the naked eye.


 

There are free viewing machines (mechanical binoculars) that assist visitors in visualizing some of the drawings. These are not always optimal as dust and dirt on the lenses and loss of definition related to location in such a harsh environment degrades the lenses.

NOTES:

I am not suggesting that people be allowed to approach these ancient treasures and, as demonstrated above, perhaps it is a good thing for their own protection.

The pictures below were not captured with a standard 35mm camera and thus the ranges given are approximately estimated for a full-frame digital camera.

With a telephoto lens ( 80mm +/-), we can get closer…





At approximately 300 mm (+/-) the drawings become quite clear:


 



Moving in a bit closer, we can see even more detail.


 

At the maximum length of the crop sensor lens on my canon HS50xs Powershot, we get a closer look, but some detail is blurred.



Once again, we see similarity to petroglyphs from other sites.

 

Tours by the Old Pueblo Archaeology Center are available for some of the petroglyph sites at the Petrified Forest.

A Pungent and Invasive Weed in the Desert

There is a pungent smell in the air this spring in our Sonoran garden and surrounding neighborhoods. It isn’t really a bad smell, but it cannot be described as a totally pleasant one either. When we first discovered this fragrance several weeks ago, we couldn’t figure out the source, but over the ensuing time period we discovered its origin.

You can see the culprit in the picture below…



and here it is again.



This yellow plant is called Globe chamomile (Oncosiphon piluliferum). While seeds can be bought for Globe chamomile, I am sure most gardeners consider it a weed.

Because of the frequent and substantial winter rains, these yellow weeds are pervasive throughout open areas in the Phoenix/Scottsdale, Arizona corridor.

You can see how thick it grows. It can be pulled out by the handful.





Globe chamomile is a South African native and it has found its way to various regions of the United States and other countries.

It has been in bloom for weeks, but the drier and warmer spring weather is now causing some die off. Notice the brownish stems (below). The flowers are still quite vibrant and fragrant, but they are definitely on the wane.



It has been blamed by many in the area for their severe outbreak of allergy symptoms. Melanie Dunlap, a Naturopathic practicioner, writes about here experience in this article titled Goddess of Allergies

Photography Video: Tag Responsibly or Don’t Tag


To Tag or Not to Tag. That may be the Question.

Photo Via Petapixel

If you follow my posts on this blog, you probably noticed that I do a fair amount of hiking. We generally visit two national parks or national park-like areas each year. At each location we spend between one or two weeks.

Prior to our trip, we plan the trails and vistas we would like to see. There are often sights that are iconic and of course we like to visit them and take some photographs for our collection. Often, however, we are way off the beaten path when we see some stunning and perhaps more pristine areas.

I have often discussed the idea of keeping these areas as natural as possible with as little human impact as feasible. After all, this is the home of the native flora and fauna.

The negative aspects of tagging photographs with exact geographic locations has been debated for a number of years. The video below – created by Jackson Hole, Wyoming – highlights the seriousness of this problem.

Personally, I don’t use specific tags with my photographs. I may include a general location such as the name of the National Park, City or State, but that is all.

What are your thoughts.

Ironwood Trees in the Sonoran Desert

My wife and I feel very fortunate to live in North Phoenix in an area that is considered “the desert.” It has its issues of course such as all the animals that want to eat our plants, invade our house and bite or sting us. Other than that, it is a beautiful area. No, really! It is very beautiful. So many people think of the Sonoran Desert as a desolate place, but it has a lot of color, a variety of plants and flowers and of course an abundance of animals.

We get pleasure from the natural landscape that surprises us with waves of color during certain times of the year. One such plant that found a home on our land without any human help is an Ironwood tree. It is amazing how this tree can survive with all of the animals digging holes around the roots and the dearth of water. Truth be told, I do “sneak” some extra water to it now and then although it doesn’t like our household water too much because of the salts and chlorine.

Here is a picture of the Ironwood tree that has seen its share of trials and yet it continues to provide a blanket of pink each spring. My only regret is that it wasn’t near one of our Palo Verde trees for the photo which, this year, have been covered with an overabundance of yellow blooms. Did someone say pollen?
