The former territory of the Sastean family is the region drained by the
Klamath River and its tributaries from the western base of the Cascade
range to the point where the Klamath flows through the ridge of hills
east of Happy Camp, which forms the boundary between the Sastean and the
Quoratean families. In addition to this region of the Klamath, the
Shasta extended over the Siskiyou range northward as far as Ashland,
Oregon.
