The Lençóis Maranhenses National Park (Parque Nacional dos Lençóis Maranhenses) is located in Maranhão state. It is an area of low, flat, occasionally flooded land, overlaid with large, discrete sand dunes. It encompasses roughly 1500 square kilometers, and despite abundant rain, supports almost no vegetation.
Located in Maria Island, a mountainous island off the east coast of Tasmania, the Painted Cliffs are sandstone with beautiful patterns formed through staining by iron oxide. Recently sea spray hitting the rock face has dried to form crystals of salt.
The Grand Prismatic Spring is the largest hot spring in the United States, and the third largest in the world. The vivid colors in the spring are the result of pigmented bacteria in the microbial mats that grow around the edges of the mineral-rich water. The bacteria produce colors ranging from green to red.
Added to UNESCO World Heritage in 1979.
