The yellow dot marks the location of the Apollo 16 landing site. Apollo 16 landed on April 21st 1972, some 30 miles (50km) west of the Kant plateau. This was the first and only attempt to land in the relatively rough lunar highlands. At the landing site a few of the small craters were found to have glass-coated bottoms resembling cracked and wrinkled dry mud in appearance. The large degraded crater along the bottom edge of the picture is Descartes (30 miles or 48 kilometers in diameter). Using the lunar rover, the astronauts made visits to the surrounding craters.
