Garry C. Rogers of the Geological Survey of Canada speculated in his 1981 NRC Research Press article "McNaughton Lake seismicity—more evidence for an Anahim hotspot?" that earthquake swarms at McNaughton Lake (now called Kinbasket Lake) may be related to the Anahim hotspot. Rogers noted that if the seismicity is related to a hotspot the surface expression must be lagging behind the passage of the hotspot. An alternative theory proposed by Rogers is that if the Anahim hotspot is located under the Wells Gray-Clearwater area, the stress field surrounding the hotspot must precede it by approximately .
