Ryder Crater

Description:

Impact craters take a wide variety of shapes, usually varying from circular to elliptical. The shape of Ryder crater is not either, it might best be called a snowman. But how? It formed on a steep ridge, which certainly was a factor. Perhaps it formed by the impact of a split asteroid? As with most complicated geologic problems, the real answer is likely some combination of processes.
