The Will showing is a road ditch outcrop at the base of outcrop on the south side of the Salmon River valley. It probably is the basal part of the Eocene Kamloops Group. Extensive overburden does not allow any assessment of the extent of the kaolinite-bearing rocks. The kaolinite was identified by x-ray diffraction of untreated and heated samples (1 hour @ 550 degrees Celsius).
