The Rinconada Canyon section has a trail one mile long that follows the base of a slope covered with jumbled boulders. Here is a large rock with a bird, what might be a bird spirit, and a horned head.
The same bird spirit petroglyph appears again next to this propped slab. There's nothing on the face of the slab. This does look like it was done recently, perhaps by local Indians, or more likely by vandals who chisel out petroglyphs for black market art sales.
The petroglyphs face to the south or southeast. The park's explanation is that they were carved in winter and the south-facing rocks would have been warmer and free of ice.
Here is a whole human figure, that seems to be dancing.
This horned snake is related to the horned and plumed snake of Mesoamerica.
Here and at Bandelier are petroglyphs of macaws, indicating trade with Mesoamerica.
There are many other images such as horned toads, antelope, rats, human faces, dancing figures, hand and foot prints, stars, and spirals.
This very familiar shape is a sacred symbol. One interpretation is that it represents a mountain, the source of game animals and water. According to Adolph Bandelier in The Delight Makers, this is a cloud, which is the ladder to heaven.
Whatever the true meaning of this sacred design, it was adapted into mission churches. Here is San Geronimo Church at Taos Pueblo.
A pleasant surprise was this enclosure on top of the mesa at Boca Negra Canyon, facing east towards Sandia Peak. The caption describes it as hunting blind or temporary shelter, later used by Spanish sheepherders. The trail up to this mesa is heavily decorated with petroglyphs, including dancing figures, suggesting this enclosure had some spiritual use.
