More than 300 petroglyphs are engraved.
Animal figures Shapes and features enable the species to be discriminated. Most of them are whales and concentrated on the left main rock face.
Ungulate mammals like deer and predatory animals like tigers, leopard, and wolves are mainly on the right main rock face. Animals whose species can be identified include large cetaceans such as the
northern right whale, the
humpback whale, the
right whale, the
gray whale, and the
sperm whale. There are also sea animals such as sea turtles, seal, salmon-like fish; sea birds; and land animals such as
red deer,
musk deer,
roe deer,
water deer, tigers, leopards, wolves, foxes,
raccoon dogs, and
wild boars. Sea birds are always placed around whales as they are hunting prey. Some engravings show mating and molt scenes of land animals and because of different patterns and angle of fall suggest the annual change of seasons and the breeding season.
Tools Tools relating to hunting and fishing such as boats, floats, harpoons, fishing net, fish pounds, and bows provide information on the age of the rock art and livelihood of the time. This site also has scenes of whales and tigers being captured with a net. Although no prehistoric net has yet been excavated, fine marks of net on pottery discovered in the
Dongsam-dong Shell Midden suggest that nets were widely used not only for fishing but also for hunting in those days. The site has scenes showing whaling activities in great detail. Around 5–17 people are on boats surrounding whales. The bows and sterns are semi-circular and are connected to a harpoon stuck into the body of whales and to floats hanging on a rope. The tools are almost identical to those used by natives for whaling today.
Indeterminate figures Engravings of uncertain theme and content have been classified into two types: those of unknown theme which are in good condition and those of unknown shape which have been worn and damaged over time and are therefore hard to decode. Some have signs with certain patterns, but it is hard to classify them on the basis of engravings on the rock alone. Signs are conceptual expressions that are impossible to find in real life but are repeated expressions of a certain pattern. ==Dating==
