The site of the village is on the McCloud River at the mouth of Kabyai Creek across the river from the McCloud Bridge Campground in the Shasta–Trinity National Forest, in Shasta County, California.^[1] The village site is among those of the Winnemem Wintu being threatened with being submerged by Shasta Lake if the proposed raising of Shasta Dam occurs.^[2][3]
