Is Alaska has the world's oldest pyramids? If so, recent snow & ice melt will revea more ancient structures. A small team of explorers has just announced that they have indeed found 2 ancient pyramids. Only the upper portions of the pyramids are exposed but the general shape is obvious. The outer rock edges of 1 pyramid & the stones were obviously stacked 1 on top of the other, bigger than Giza's. The accidental discovery was made during a hike & pictures of the pyramids are in this pin.
