             extract from the image's caption:  Weird terrain best describes this hilly, lineated region of  Mercury. Scientists note that this area is at the antipodal point to the large  Caloris basin. The shock wave produced by the Caloris impact may have been reflected and focused to the antipodal point, thus jumbling the crust and breaking it into a series of complex blocks. The area covered is about 800 km (497 mi) on a side.
