Whetherthe suspected changes have been merely illusions dueto variable illumination, or are a reality, has not beendefinitely decided. Although the majority of the lunar elevations assumethe crateriform aspect, a number of long and loftyranges of mountains, resembling terrestrial mountains,exist on the Moon. The lunar mountains, it may benoted, are not only relatively but actually higher thanthose of the Earth. Mt. Everest, the giant of theHimalayas, the loftiest mountain in the world, is onlya trifle more than 29,000 feet high, while several peaksof the Leibnitz Mountains on the extreme southernedge of the lunar disk are nearly 30,000 feet, and onepeak is even said to be 36,000 feet in height. There are. Yerkes Observatory Plate XXIX. The Great Lunar Crater Copernicus The Moon 349 more than forty lunar mountains that are higher thanis Mt. McKinley, Alaska, the highest peak in NorthAmerica, its height being only 20,464 feet. Of thelarger mountain ranges, most of which are named afterterrestrial mountains, the best known are the LunarApennines, the Lunar Alps, the Lunar Caucasus, theLunar Carpathians, the Lunar Pyrenees, the Leibnitz,and the Doerfel Mountains. They are best viewedwhen the moon is in its first or last quarter. The Lunar Apennines (Plate XXX.) named byGalileo after the Apennines of Italy, are the greatestand most impressive of the larger mountain are upwards of four hundred miles in length, andwhile many of the peaks are from 12,000 to 20,000 feethigh, one in particular attains to the height of 22,000feet.
