223 – In A Different Light

Several of the boulders in the rock shelter have petroglyphs, grinding slicks, or both. The panoramic slideshow below shows four of these boulders. The photos were taken with a flash at a steep lighting angle, to highlight the features present.

These Reflectance Transformation Imaging (RTI) views of the main petroglyph panel at WACA 223 allow you to change the lighting angle to pick out additional details.
