Terraced Mercurian Craters (HR)

This crater (about 98 km diameter) illustrates the narrow hummocky rim facies, radial ridges and surrounding extensive field of secondary craters.
The well-developed interior terraces and central peaks are typical for Mercurian Craters in this size range.
Note that the smaller craters in the foreground (25-Km diameter) also are terraced.
