Rosenberg is a typical highlands crater - old enough to have lost is freshness and most of its terracing (despite what Elger writes). It has a broad flat floor and just a small central peak.
(IAU Directions) ROSENBERGER.--This formation, about 50 miles in diameter, is one of the remarkable group of large rings to which Vlacq, Hommel, Pitiscus, &c., belong. Its walls, though of only moderate altitude, are distinctly terraced. In addition to a prominent central mountain (W. of which Schmidt shows two craters), there is a large crater on the S. side of the floor, and many smaller craters and crater-pits.
