This image shows a lava channel north of Kuiper Crater in the high southern latitudes just before spring equinox. It was a target suggested by members of the public, using our suggestion tool called HiWish.
The channel confluence at the top of the image illustrates interesting volcanic processes that took place long ago. However, it was the mounds on the rim of the channel to the south of the confluence that we initially found alarming. These mounds, up to 400 meters in diameter, are decorated by radial and concentric patterns that resemble spider webs. [More at link]
