The Camelsfoot Range, north of Lillooet, is included in the Chilcotin Plateau by some systems of classification.

Also draining the plateau on its eastern edge is Churn Creek, which forms the east flank of the Camelsfoot Range and enters the Fraser directly.

On the west side of the plateau, the basins of the Dean, Homathko and Atnarko Rivers penetrate the massifs of the Coast Mountains and have their beginnings, or the early part of their courses, on the Chilcotin Plateau.

[1] It extends along the adjacent Garibaldi Volcanic Belt in the Coast Mountains.

Volcanism of the Chilcotin Plateau is considered to be related to back-arc basin crustal extension behind the coastal Cascadia subduction zone.
