This Magellan full-resolution mosaicked image shows an intermediate-sized volcano about 50 kilometers (31 miles) in diameter. This volcano is located in northern Lada Terra at 42.6 degrees south latitude, 27.9 degrees longitude. The volcano has a central caldera-like structure (depression) about 12 kilometers (7 miles) in diameter, surrounded by an asymmetrical ring of narrow flows that extend for 15-to-40 kilometers (9-to-25 miles). To the north and northeast, an apron of older lava flows underlies the annulus and extends up to an additional 60 kilometers (37 miles). The darker stripes within the mosaic are an artifact of the radar collection; these are individual orbits in which the spacecraft's antenna was pointing very slightly off-target
