The volcanic edifice is an elongated, flat cone of about 1650 m height. No definitive answer has proven exactly what is keeping the Rockies afloat yet, but it is believed to be a combination of very dense crust underneath the mountains (Pratt isostasy) and hot underlying mantle supporting the range's weight. When one of the plates is an oceanic plate, it gets embedded in the softer asthenosphere of the continental plate, and as a result, trenches are formed at the zone of subduction.

The directional trend of both the cordilleras generally is north-south, but in several places the Cordillera Oriental bulges eastward to form either isolated peninsula-like ranges or such high intermontane plateau regions as the Altiplano (Spanish: High Plateau), occupying adjoining parts of Argentina, Chile, Bolivia, and Peru. The highest of them is Mount Aconcagua (22,831 feet [6,959 metres]) on the border of Argentina and Chile (see Researchers Note: Height of Mount Aconcagua).
