The tribe subsisted on fish and root vegetables, and constructed large cedar platforms to dip their nets in over
Willamette Falls to harvest salmon. The Clackamas women dried and smoked the salmon, which they then combined with mixtures of berries and nuts, preserving it in woven baskets for winter. The Clackamas traded salmon with other tribes, and also harvested and traded
wapato, broad-leafed arrowhead or "Indian potato" (
Sagittaria latifolia and
Sagittaria cuneata). Adult Clackamas historically wore leather leggings and tunics, and made skirts and bedding from cedar bark. An indication of high status in the tribe was intricate
beadwork,
quillwork, feather, and shell decorations. Certain shells served as currency. Like others of the
Chinookan peoples, Clackamas practiced
head flattening. From infancy, one's head was compressed between boards thus sloping the forehead backward. This was a way to indicate that a person was free rather than a slave. The Clackamas were expert woodworkers, and crafted canoes and plank lodges. A typical canoe was 20 to 30 feet long, which they used to travel along the rivers, transporting trade goods and people. With deep knowledge of the Clackamas river systems, the Clackamas were often hired by pioneers as guides to navigate the river systems. == Tomanowos ==
