The rim of Mädler is irregular and somewhat oblong in shape. There is a low central peak that joins a ridge crossing the floor. To the east of the crater are ray markings that include a ring-shape to the northeast. The infrared spectrum of pure crystalline plagioclase has been identified on the southeastern rim.[2]
