Geography

Mount Ritter is made of strikingly dark rock and is quite prominent due to its height and isolation.[1] It is in the middle of the Ritter Range, which includes neighboring Banner Peak and the Minarets. The prominent and memorable shape of the Ritter–Banner pair is visible from high elevations far to the north and south in the Sierra Nevada.

Mount Ritter was named by Josiah Whitney, chief of the California Geological Survey, for Carl Ritter, who had been a teacher of his when he was a student in Berlin during the 1840s.[5]
