Yupu
Yupu stood at the meeting of the Yuba and Feather Rivers in the northern Sacramento Valley. Its name was also recorded as Yuba and Yubu. The village belonged to the Nisenan, whose communities occupied river valleys and foothills east of the Sacramento. Fishing places, oak groves and the surrounding lands supported the inhabitants of this river junction. In 1833 a severe epidemic, believed to have been malaria, struck the Nisenan of the valley and caused great loss of life.
