The images are anthropomorphic, part human and part animal
The pigments from the rocks were mixed with animal fats and other natural binders
The canyon dwellers survived for over 2000 years from hunting deer, rabbit, small mammals, and occasionally bison during wet climates. The inhabitants also utilized the desert vegetation as sustenance, such as, agave, sotol, peyote, prickly pear cactus and other seasonal plants and fruits. The canyons were fed by springs and rain lending to an oasis like environment.
The root was boiled and eaten, at bottom right. The root also makes a liquor like agave tequila.
Spring fed canyon with lush vegetation
The rock shelter provided protection from the sun and rain. The reddish and black colors along the bottom are deteriorated images that once adorned the canyon walls.
According to our State Park guide, the canyon dwellers of the Lower Pecos are one of the longest continuous civilizations in history. My father said Egypt, but the natives of the Lower Pecos lived in a small canyon region with a similar lifestyle and culture for over 2000 years. Most of the ancient sites are on private land. There are 250 canyon shelters in Texas and another 50 or so in Mexico. Seminole Canyon was donated to the state by a cattle farmer in the late 1970's. The archeological studies are recent and there is much more analysis needed. A guided tour is necessary to view the ancient rock art to avoid potential acts of graffiti. There is hiking in the state park along the canyon rim for spectacular views across the desert and into the canyons including a Rio Grande overlook. Camping sites are also available. Regretfully, Cody and I only visited the park for a day. There are many more guided tours to several other pictograph sites and some only accessible by boat (possible future canoe trip).

Hiking the Canyon Rim
The Seminole Canyon Rock Art is rapidly deteriorating due to the increased humidity from Lake Amistad. The Rock Art Foundation is a nonprofit "that promotes the conservation and study of Native American Rock Art in the Lower Pecos Region." If you are interested in contributing to the preservation of native art visit http://www.rockart.org
Seminole Canyon is a fantastic opportunity to visit the people of the past. It's not a museum exhibition but a real place in time. A great book about the Lower Pecos canyon dwellers is Peyote Fire: Shaman of the Canyons by Mary S. Black. The novel is about a man becoming a great shaman and bringing the peyote medicine back to his people. There are some graphic hunting scenes based on real archaeological findings.

As an anthropologist I found this book fascinating and helpful to understanding the rock art and the native people. Carolyn E.
