Doris Lundy has studied the different rock art sites in the Northwest. She found 621 sites total, and about 46% had petroglyphs, 53% had pictographs, and about 1% had both or couldn't be determined. She says most of the pictograph sites were on shores of rivers and lakes on light-colored rocks, but the petroglphs were usually on sandstone and face the ocean and are often found underneath the water at high tide.
The petroglyphs weren't heavily detailed because they were pecked really deep, and therefore detail couldn't be done. The eyes of the anthropomorphs or the zoomorphs tend to be the focus of the drawings. For instance, some of eages and whale petroglyphs have the "weeping eye" (it appears to be crying). Females are often shown to have "labrets"-ornamental pieces worn in holes pierced in the lower lip.
Figure 6: (Wellman, picture C-3) This is a pictograph of Tsagaglalal (meaning "she who watches over"), a mythical women ruler who was turned to stone by Coyote. She supposedly displays the labrets.
Common Themes in the rock art: Whales, Faces-both outlined and non-outlined, birds-mainly the thunderbird and eagles, women with their legs spread (and sometimes including the bisected oval) or men with enlarged penises. Also, many of the anthropomorphs in the Bella Coola region have bent arms and legs, causing them to appear froglike. The zoomorphs include many sea mammals, birds (including blue jays, eagles, puffins, and the thunderbird), killer whales, wolves, and salmon (both alive looking and the skeletons). There are not a whole lot of quadrupeds, but there are some examples of deer, wolves, bears, mountain goats, and horses. Also, there are many animals with the X-ray look (like in Australia), and also things called "sea monsters". Some of the sea monsters look like the Old World dragons with flaring nostrils and open mouths with sharp teeth, but many have wolf-characteristics as well.
Non-animal themes include coppers, labrets (the symbol indicating "female"), canoes, sailing ships, and other manufactured objects. There are also geometric symbols like spirals, concentric circles, triangles, rayed circles, etc either randomly distributed or in a pattern. Lundy found that there are more geometric designs than anthropomorphs or zoomorphs. What is especially interesting is the lack of handprints and footprints. There have been a total of 2 handprints and 1 footprint recorded in the Northwest.

Grant categorized the northwest rock art into 4 categories:

Another myth is about a salmon who becomes a man, marries and takes his bride into the sea to return later with his salmon friends to be caught so the Native Americans could have food.
Many sites may have shamanistic rites connected to them. There is evidence of offerings left at some of the sites which may indicate shrines. Also, the high amount of masks-both pecked and carved- suggest Shamanism. In addition, the x-ray rib bones symbolize the rebirth of the shaman. The "blind eye" (one eye is filled in while the other is round) is a symbol of spiritual power, and therefore shamanism.
