Rano Raraku, one of two extinct volcanoes on Easter Island, is best known for the hundreds of moai statues scattered across its slopes and inside the crater, many of which have been partially buried over the years by erosion from the volcano’s upper slopes, disguising their monumental scale. While most of the island’s moai face away from the coast, several of those on Rano Raraku look towards the sea, leading historians to speculate that they may have been intended for sites elsewhere on the island. The base of the caldera is covered with a lake, one of only three natural sources of fresh water on the island.
