Part of the Moon's surface showing craters and mountain chains. The double crater Theophilus, seen near the Moon's left edge is 64 miles across. Its circular walls rise 18,000 feet above the floor, and its tallest central peak, calculated from shadow length, is 6,000 feet high. A steep ridge runs from Theophilus to the ring plain Beaumont. M├Ądler, a small ring plain 20 miles in diameter, lies to the left of the crater. Photograph taken at the Cassegrain focus of the 82-inch McDonald Reflector.
