It takes many people to raise a finished totem pole – over 100 to carry it and many more to dig the hole that holds the base. The pole is leaned into the hole with ropes tied around it; many people then pull on the ropes to get it upright. Raising the totem pole was cause for special ceremonies and a great feast, called a “potlatch.”
