The Sierra Nevada de Santo Domingo of Mérida (commonly referred to as the Sierra de Santo Domingo) is a mountain range belonging to the Sierra Nevada National Park, which extends across the western part of Venezuela, specifically through the states of Barinas and Mérida. It sustains elevations above 3,500 metres (11,500 ft) above sea level. Geologically, it shares one of the oldest rock substrates in Venezuela's stratigraphic record and the greatest geological age yet found in the Venezuelan Andes. These consist of metamorphic and igneous rocks belonging to the Upper Precambrian, with ages of approximately 600 million years, grouped under the designation of the Iglesias Complex. During the Quaternary, cooling conditions allowed the Sierra de Santo Domingo to be covered by mountain glaciers in valleys situated above 2,900–3,000 metres (9,500–9,800 ft) above sea level.
