The Ingram showing is located 13 kilometres southwest of Falkland, at the edge of the plateau near Ingram Creek.
In this area, Upper Triassic to Lower Jurassic Nicola Group sedimentary and volcanic rocks unconformably overlie sedimentary and volcanic rocks of the Devonian to Triassic Harper Ranch Group. These units are intruded by Middle Jurassic granitic rocks. Extensive Eocene Kamloops Group volcanic and sedimentary rocks overlie the older units.
Kamloops Group basalt flows host agate. The agate comes in various shapes and colours.
