Geophysics survey, Lake Purdigulac, 2009. -38.260268, 143.499328
Purdigulac is a nested maar complex of multipe vents and some scoria cones. It lies south of the Red Rocks complex and right in the middle of the Eastern Volcanics. It was a pain to survey as the lake occasionally fills with water and the concentration of salts creates meter deep cracks in the sediments at the bottom of the craters during dry times. Flicity (volcanologist), Tegan (volcanolo-physicist) and I (geo-physicist) quite enjoyed our time exploring this volcano.
An image of the Red Rocks complex taken nabbed from the AltonaBeauty blog. Purdigulac is part of the Red Rocks Complex which contains at least 9 craters and a number of scoria cones. Work by Teagan Blakie and Flicity Piganis has identified that Purdigulac is one of the most complex craters in this complex with at least 9 eruptive points and shallow diatreme structures with multiple coalescing vents.
