Mount Schank is a small, well preserved volcanic cone about 12km south of Mount Gambier, near the main Mount Gambier, near the main Mount Gambier to Port MacDonnell road. Although 160m high is one of the few prominent landmarks in the areas. (Plate 1). It belongs to the younger phase of volcanic activity in the area, the most recent activity being approximately 1,400 years Before Present. The cone is essentially composed of well layered volcanic ash, with basaltic lava flows to the west. The volcanic ash and cinders are being excavated in a quarry on the eastern flank of the cone itself (Plate 4), while the lava is being excavated in a quarry to the west of the cone (Plate 3).
