Tower Hill maar, with bedded pyroclastic layers exposed in its wall, is part of the voluminous Newer Volcanics Province, which covers a broad 15,000 km² area of SE Australia. The volcanic field contains nearly 400 vents, with late-Pleistocene to Holocene eruptions producing scoria cones, maars, tuff rings, and valley-filling lava flows. The most recent eruptions took place at Mount Schank and Mount Gambier.
