Tree and volcanic strata, Tower Hill Posters and Art Prints

Tower Hill, in Victoria, declared Victoria's first National Park in 1892, was formed at least 30,000 years ago when a hot rising basaltic magma came into contact with the subterranean water table. The violent explosion that followed created the funnel-shaped crater (later filled by a lake) and the islands seen today. Artefacts found in the volcanic ash layers show that Aborigines were living in the area at the time of the eruption. The Warrnambool area was a rich source of foods for the Koroitgundidj people, whose descendants retain special links with this country.
