Eurasian Basin Eurasian Basin The Eurasia Basin, or Eurasian Basin, is one of the two major basins into which the Arctic Basin of the Arctic Ocean is split by the Lomonosov Ridge (other being the Amerasia Basin). The Eurasia Basin may be seen as an extension of the North Atlantic Basin through Fram Strait. It is further split by the mid-ocean Gakkel Ridge into the Nansen Basin and the Amundsen Basin. The latter basin is the deepest one of the Arctic Ocean and the geographic North Pole is located there. The Eurasia Basin is bounded by Greenland, the Lomonosov Ridge, and the
Closed Basin Project end from the Rio Grande watershed. It contains the towns of Center, Hooper, Moffat, Mosca and Saguache and the Great Sand Dunes National Park and Preserve. Streams that flow into the basin include irrigation diversions from the Rio Grande, the Carnero, La Garita, and Saguache creeks from the west, San Luis Creek from the north, and the North Crestone and Sand creeks from the east. The water spreads over the floor of the valley and either sinks into the underground aquifer or evaporates. The lowest part of the basin extends from the San Luis lakes north to the Blanca Wildlife
