Graffiti (Inventory)/Pictographs
From LagWiki
The Pictographs field of the Graffiti section should be used to record stations where pictographs are observed.
A pictograph is a drawing or form of symbolic artwork that can be found within caves. True pictographs are very historic and of significant cultural anthropological importance. Pictographs are most often found near the entrance, in the twilight portion of the cave. The symbolic artwork may or may not be recognizable and because of age, it may even be very hard to identify. Red ochre, yellow ochre, charcoal black and white are common colors in pictographs. The pigments were often made of whatever colorful material could be collected.
For purposes of cave inventory, the definition of pictograph should be broadly construed to include similar artwork such as petroglyphs. Basically, any kind of symbolic artform on the rock is inventoried in this field.
