The newer volcanics basalt deposit were formed by series of volcanic eruptions from around 400 now extinct volcanoes from Seymour to Portland. This basalt covers an area of around 15,000km, however, since most of the individual eruptions were relatively small, and the lava was very running, in most places the deposit is less than 50m thick, but they can have traveled a long way, often in river or creek valleys sometimes filling them completely.
All of this happened only 4000 to 5000 years ago!!
