The showing is located within the Downie Slide on the west slope of the Columbia River valley. The slide mass is composed of pelitic and semipelitic schists that lie on the northeastern flank of the Frenchman Cap gneiss dome in the Shuswap Metamorphic Complex.
Kyanite crystals occur in quartz veins and pegmatites and sections of the schists over a length of 300 metres along the river.
