It is situated within the Budj Bim National Park. Budj Bim is the Gunditjmara name, meaning High Head. The roughly conical peak rises . The peak is a scoria hill that was thrown up beside a group of three overlapping volcanic craters that now contain Lake Surprise. A line of smaller craters and scoria cones runs to the southeast. Lava flows extend to form a shield volcano and are fed by several lava channels, or lava canals as they are known locally. This lava flow, known as the Tyrendarra lava flow, changed the drainage pattern of the region, and created large wetlands.
