Parts of the white silts along the Thompson Valley were used for common brick. A sample taken from a 0.9 metre thick bed of clay at road level from the banks on the cliffs below a communications tower site, south of the subdivision of Valleyview, indicated that the clay did not have value as a raw material for ceramic products. Bedrock geology consists of argillite, sandstone and tuff of the Upper Triassic Nicola Group.
