Americas
The largest mountain ranges are the Andes and Rocky Mountains. The Sierra Nevada and the Cascade Range reach similar altitudes as the Rocky Mountains, but are significantly smaller. In North America, the greatest number of fourteeners are in the United States, and more specifically in the U.S. state of Colorado. The highest peaks of the Americas are located in the Andes, with Aconcagua of Argentina being the highest; in North America Denali (Mount McKinley) in the U.S. state of Alaska is the tallest.
Opiliones
Several Opiliones in Argentina appear to be vulnerable, if not endangered. These include "Pachyloidellus fulvigranulatus", which is found only on top of Cerro Uritorco, the highest peak in the Sierras Chicas chain (provincia de Cordoba) and "Pachyloides borellii" is in rainforest patches in northwest Argentina which are in an area being dramatically destroyed by humans. The cave-living "Picunchenops spelaeus" is apparently endangered through human action. So far, no harvestman has been included in any kind of a Red List in Argentina, so they receive no protection.
