The Los Glacia­res Nation­al Park is an area of excep­tion­al nat­ur­al beau­ty, with rugged, tow­er­ing moun­tains and numer­ous glacial lakes, includ­ing Lake Argenti­no, which is 160 km long. At its far­thest end, three glac­i­ers meet to dump their efflu­via into the milky grey glacial water, launch­ing mas­sive igloo ice­bergs into the lake with thun­der­ous splash­es.
