'Moving its cameras southward and towards the terminator [of Mercury], Mariner 10 took this series for a mosaic centered about 135° longitude and 30°S latitude. The mosaic is dominated by a bright-ringed large crater almost at its center. Just above it is a large basin that shows a ruined inner ring.' (James A. Dune, The Voyager of Mariner 10, Washington, DC: NASA Scientific and Technical Information Office, 1978)
