Konkow
Konkow Maidu communities lived along the North Fork of the Feather River and its tributaries in northern California. Each group of villages had a large, partly subterranean ceremonial house, the k'akkinimkumi, at its principal settlement. Acorns were dried and stored, while salmon returning up the Feather River supplied another important food. Konkow traders exchanged salmon, pine nuts, deer hides, bows and arrows for obsidian, beads and green pigment. In 1833 a severe epidemic, possibly malaria, devastated Konkow and neighbouring communities of the Central Valley.
