The Canyon area is underlain by gently dipping rocks of the Proterozoic Shuswap Terrane consisting of gneiss and schist. Kettle Valley Stone Company produces decorative rock from the gneiss. Records indicate production was occurring at the quarry as early as 1999 and was ongoing in 2005. Production may have occurred prior to 1999. The product is marketed as “Rainbow Granite”.

By 2004, the Kettle Valley Stone Company of Kelowna employed about 40 people year round, mainly at its processing plant where raw material is brought from several quarries including the Canyon.
