El Calafate, also known as Calafate, is a city in Patagonia, Argentina. It is situated on the southern border of Lake Argentino, in the southwest part of the Santa Cruz Province, about 320 kilometres (200 mi) northwest of Río Gallegos. The name of the city is derived from a little bush with yellow flowers and dark blue berries that is very common in Patagonia: the calafate ; the word comes from the word calafate, which is Spanish for 'caulk'.
