Along the western and eastern seaboards, and in the southern half of North America, Indians made dug out canoes. They were made of a single log. To shape the inside where travelers sat, they used a controlled burning technique, and then hollowed out the burnt wood. Northwest Coast Indians had elaborately carved images on the bow and sides on these seagoing canoes. The average size was between 20-30 feet long. However, the boats could reach up to 60 feet and carry 30-40 men.
