25954198IslandIsland in the Xingu River, in the Great Loop ("Volta Grande") section between the cities of Altamira and Senador José Porfírio, PA. Name unknown.
The island is separated from its eastern neighbor by a very narrow channel.
The polygon follows the vegetation outline, excluding flat barren areas (sandy or rocky) that are probably submerged in the rainy season. Caveat: the northernmost 1/4 of the outline comes from poor cloud-obscured images and is rather uncertain.-51.7767298-3.5078845BrazilAmapaOiapoque24332-3.4980753-3.5176937-51.771816-51.7816436
