Petroglyph National Monument - Boca Negra Canyon

Between Bernalillo and Albuquerque is the Petroglyph National Monument (among other things and places). We visited one small section of this 7,000+ acre monument, Boca Negra Canyon.

From the National Park Service,

Petroglyph National Monument protects one of the largest petroglyph sites in North America, featuring designs and symbols carved onto volcanic rocks by Native Americans and Spanish settlers 400 to 700 years ago. These images are a valuable record of cultural expression and hold profound spiritual significance for contemporary Native Americans and for the descendants of the early Spanish settlers.

What we found was an area covered with a jumble of dark rocks, many of which had designs scratched onto them.

Many designs were not really anything I could identify.

Others were clearly of humans, but doing what is a mystery.

The one below seems to suggest one of the older drawings if I am any judge of such things. The person on the right just looks to me to be an older style.

This animal also appears to me to be among the older designs.

I have no idea what to make of this one. Could be from the Teletubbies or from some ancient Native American. I wondered when walking about taking photos just how the park service keeps this collection of drawings from being added to each year. Aside from the design differences, would a new one look any different (line color, line width, etc.) from an old one? I did not try to find out.
