The artists who produced these unique paintings used techniques not often observed in other cave art. Many of the paintings appear to have been made only after the walls were scraped clear of debris and concretions. This left a smoother and noticeably lighter area upon which the artists worked. Similarly, a three dimensional quality is achieved by incising or etching about the outlines of certain figures. This visually emphasizes some of the animals and allows torch light to cast shadows about the edges.
