COTOPAXI , a See also:
It is more than 15,000 ft. higher than See also: Vesuvius, over 7000 ft. higher than See also:Teneriffe, and nearly 2000 ft. higher than See also:Popocatepetl. Its slope, according to See also:Orton, is 300, according to Wagner 29°, the See also:north-western See also:side being slightly steeper than the south-eastern. The apical See also:angle is 122° 30'. The snowfall is heavier on the eastern side of the cone which is permanently covered, while the western side is usually See also:left See also:bare, a phenomenon occasioned by the See also:action of the moist See also:trade winds from the See also:Atlantic. Its height according to Whymper is 19,613 ft., and its crater is 2300 ft. in See also:diameter from N. to S., 165o ft. from E. to W., and has an approximate See also:depth of 1200 ft. It is bordered by a rim of trachytic See also:rock, forming a See also:black coronet above the greyish volcanic dust and See also:sand which covers its sides to a great depth. Whymper found See also:snow and See also:ice under this sand. On the See also:southern slope, at a height of 15,059 ft., is a bare cone of porphyritic See also:andesite called El Picacho, " the See also:beak," or Cabeza del Inca, " the Inca's See also:head," with dark cliffs rising fully See also:I000 ft., which according to tradition is the See also:original See also:summit of the volcano blown off at the first-known eruption of 1532. The summit of Cotopaxi is usually enveloped in clouds; and even in the clearest See also:month of the year it is rarely visible for more than eight or ten days. Its eruptions produce enormous quantities of See also:pumice, and deep layers of mud, volcanic sand and pumice surround it on the See also:plateau. Of the See also:air currents about and above Cotopaxi, Wagner says (Naturw. Reisen See also:im trop.Amerika, p. 514) : " On the Tacunga Plateau, at a height of 8000 See also:
