The glacier and its surroundings officially became Perito Moreno National Park in 1937, with the aim of protecting the lenga forests and two important lake systems that include glaciers, waterfalls and a portion of the Patagonian steppe.
Ice blocks of different sizes continually detach from Perito Moreno glacier and fall into the waters of Lake Argentino, causing spine-chilling sounds and amazing waves on the surface that make of this view an unforgettable sight.
Once in the lake, these ice floes, which may vary from white to sapphire blue tonality, are left adrift until they completely melt.
