Summary Author: Pablo Barrios
Cerro Tomolasta is an isolated peak in the southern Andes Mountains of central Argentina, in the province of San Luis. At nearly 6,621 ft (2,018 m) it’s sizeable enough to, on occasion, alter the shape of orographic clouds that form when relatively moist air is forced to rise over its elevated terrain, resulting in curious cloud formations as shown above. Here, Cerro Tomolasta is observed from a distance of about 6 mi (10 km) on January 16, 2020.
