Like Tsimshian artistic production, Gitxsan art is based on the complex organization of clans, secret society performances and potlatches, which are large feasts where name, rank or hereditary privileges are claimed through dances, speeches and the distribution of property.
Most Gitxsan art depicts myths, tales and the associated supernatural beings. Crests are represented through carvings and paintings on interior posts, totem poles, beams, rafters and ceremonial entrances.
Unique features found on Gitxsan poles include mask-like faces that are usually without a body, and not intertwined. Often figures of animals or birds (usually carved separately and attached) are on top of poles and appear to be in motion or flight.
