Lençóis Maranhenses National Park and Sediments Along Coast of Northeastern Brazil2.7S 42.8W
Sediments frame the coastline of northeastern Brazil, particularly along the states of Maranhão, Piauí, Ceará and Rio Grande do Norte (left to right).
Visible in the state of Maranhão, in the upper left quadrant, is the Lençóis Maranhenses National Park (Parque Nacional dos Lençóis Maranhenses), appearing as a large white area by the coast, just east of the Baía de São José. 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.
