The search for the EarthCache “Glaciar Perito Moreno – Patagonia” (GC1JPHG) brings geocachers to a natural wonder of South America. The Southern Patagonian Ice Field represents the world’s third largest reserve of fresh water. To claim a smiley on this EarthCache adventurers must email the answers to two questions and a picture to the cache owner. Geocachers will only be able to find the answer to the questions if they’ve arrived at the coordinates on the cache page.

Dutzig created the difficulty 2.5, terrain 2.5 cache in 2008. So far, nearly 80 geocachers have logged a “Found it.”

The cache page details the powerful potential of the “Perito Moreno Glacier.” Dutzig writes: “The Perito Moreno Glacier is one of only three Patagonian glaciers that are not retreating. Periodically the glacier advances over the L-shaped “Lago Argentino” (“Argentine Lake”) forming a natural dam which separates the two halves of the lake when it reaches the opposite shore. With no escape route, the water-level on the Brazo Rico side of the lake can rise by up to 30 meters above the level of the main lake. The enormous pressure produced by this mass of waters finally breaks the ice barrier holding it back, in a spectacular rupture event.” The last rupture of the glacier was documented in July of 2008.
