Sunrise on Mt. Tronodor in Argentina. ´Tronodor´means Thunder in Spanish because there are numerous glaciers surrounding the mountain. As these glaciers calve the thunderous sound of the pieces of ice crashing down the mountain echoes throughout the valley. We were camped about 100 yards from the edge of one of these glaciers. There was a group from the Argentinian military that was up there training on the glacier in order to be stationed in Antarctica.
