A PICTOGRAPH ROCK SHELTER IN GUADALUPE CANYON, BAJA CALIFORNIA, MEXICO.

Rock art near Guadalupe Canyon includes both petroglyph and pictograph sites. This paper documents a rock shelter in the canyon containing pictographs in both black and red pigments. The black figures were made in two styles, by painting using a black pigment and by scratching with a charcoal stick. As judged by content, superposition and preservation, the black figures (of both types) seem much more recent than most of the red figures. Because of fading and superposition, the red figures can be very difficult to make out. The DStretch rock art enhancement program was used to improve the visibility of the red figures. The abstract style of the faded red figures differs from the painted black figures, which include many anthropomorphs and animals, and from the scratched black designs. There are stylistic similarities between the faded red designs and petroglyphs found in the area. [ABSTRACT FROM AUTHOR]
