Basaltic volcanism in the form of small-volume, subaerial and subaqueous eruptions have occurred in the Wells Cray—Clearwater area of east central British Columbia. These eruptions have been dated by the K-Ar method and by relationships to dated glaciations. The oldest known eruption may be as old as Ma, but is more likely 2 Ma or less. The youngest eruptions are less than ± Cited by:

The High Lava Plains are contiguous with and gradational into the Basin and Range province to the south, and many late Cenozoic volcanic rocks and fault structures are common to both provinces. For instance, some of the larger north- and northeast-trending faults, characteristic of the Basin and Range, appear to change to a northwest trend and.
