Fossilized Ladder Ripples, Torpedo Creek Quarzite near Mount Oxide in the Western Succession of the Mount Isa Inlier, Queensland, Australia. In environments such as tidally influenced areas, water currents often go in different directions, resulting in unusual ripple patterns (hard to explain tidally influenced areas in a global flood). Torpedo Creek Quartzite is about 1.69 billion years old.
