In the same time, and the farm of Antisana, where Humboldt resided for a time, 165 ft.
Antisana is crowned with a double dome, and is described as an extinct volcano, though Humboldt saw smoke issuing from it in 1802.
On its western side is the famous hacienda (farm) of Antisana, 13,306 ft.
Sara-Urcu stands south-east of Antisana in a densely forested region, drenched with rain and only slightly explored.
All the higher summits of Ecuador have true glaciers, the largest being found on Antisana, Cayambe and Chimborazo.
Chimborazo, Iliniza, Pichincha), the ancient rocks of the Eastern Cordillera (Altar, Tunguragua, Cotopaxi, Antisana), or the floor of the great depression between.
For instance, in 1880 Whymper found permanent snow on Cotocachi at 14,500 ft., while near by Imbabura was bare to its summit (15,033 ft.); Antisana was permanently covered at 16,000 ft., and near by Sara-Urcu, which is drenched with rains and mists from the Amazon valley all the year round, at 14,000 ft.; Sincholagua had large beds of permanent snow at 15,300 ft., Cotopaxi was permanently covered at 15,500 ft.
The hacienda of Antisana, 13,306 ft., and the herdsmen's hut of Cunayaco on Chimborazo, 13,396 ft., are occupied only for a part of the year.
Of the flora of the highest Andes, Whymper found 42 species, of various orders, above 16,000 ft., almost all of which were from Antisana and Chimborazo; 12 genera of mosses were found above 15,000 ft., and 59 species of flowering plants above 14,000 ft., of which 35 species came from above 15,000 and 20 species from above 16,000 ft.
Chimborazo, which is not in the main chain, reaches 20,517 ft.; Cotopaxi (19,580), Antisana (19,260), Coyambo (19,200) are in the eastern range, with many other peaks over 16,000 ft.
The Napo rises on the flanks of the volcanoes of Antisana, Sincholagua and Cotopaxi.
