Nevado de Toluca. The Aztec name is “Zinantecatl.” Despite local belief that Humboldt ascended higher Mexican peaks, his ascent of Nevado de Toluca in 1803 was the loftiest point attained by him in that country. It is the earliest recorded ascent. Heilprin, in 1890, obtained an elevation of 14,954 ft.
