USA – June 27th, 2013

Smoke from a large fire in the Gila National Forest, in New Mexico, west of the Rio Grande (running parallel to the right edge), can be seen fanning out over a great area as it blows westward. The Gila National Forest covers approximately 2,710,659 acres (1,100,000 ha) of public land. Terrain ranges from rugged mountains and deep canyons to semi-desert. Due to the extremely rugged terrain, the area is largely unspoiled.

Interconnected Lagoons by Brazil-Uruguay Border: Lagoa dos Patos and Lagoa Mirim

Uruguay, Brazil, Argentina - May 17th, 2012

Visible near the shoreline in the upper part of this image is the Lagoa dos Patos (meaning Lagoon of the Ducks), the second largest lagoon in Latin America and the biggest in Brazil. It is located in the state of Rio Grande do Sul, southern Brazil.

The lagoon is 174 miles (280 km) long, has a maximum width of 44 miles (70 km), and a total area of 3,803 sq. mi. (9,850 km). It is separated from the Atlantic Ocean by a sandbar about 5 miles (8 kilometers) wide. The navigable São Gonçalo Channel, which enters Lagoa dos Patos near the town of Pelotas, connects Lagoa dos Patos to Lagoa Mirim to the south.

Lagoa Mirim (or Laguna Merín in Spanish) is a large estuarine lagoon which extends from southern Rio Grande do Sul state in Brazil into eastern Uruguay. Lagoa Mirim is separated from the Atlantic Ocean by a sandy, partially barren isthmus.

Lagoa Mirim is about 108 miles (174 km) long by 6 to 22 miles (35 km) wide. It is more irregular in outline than its larger neighbor to the north, Lagoa dos Patos, and discharges into the latter through São Gonçalo Channel. Lagoa Mirim has no direct connection to the Atlantic, but the Rio Grande, a tidal channel about 24 miles (39 km) long which connects Lagoa dos Patos to the Atlantic, affords an entrance to the navigable inland waters of both lagoons and several small ports.

USA and Mexico - November 17th, 2011

The Amistad Reservoir, visible in the center of this image, is a lake on the Rio Grande at its confluence with the Devils River. The lake stretches across the international border between USA and Mexico, and is bounded by Val Verde County on the Texas side of the border, and the state of Coahuila on the Mexican side.

The reservoir was formed in November, 1969 by the construction of Amistad Dam to provide flood control, water conservation, irrigation, hydroelectric power, and recreation to the area. The dam and lake are managed jointly by the governments of the United States and Mexico through the International Boundary and Water Commission.

The large white area near the bottom of this image of New Mexico, USA, is the sand dune field known as the White Sands National Monument. The field has a surface area of 710 km² (275 mi²).

The thick, dark brown line just north of the dunes is the Carrizozo Malpais, a large lava flow. Another volcanic feature can be observed to the west of the lava flow: the Jornada del Muerto Volcano. It is a small shield volcano and lava field in central New Mexico that is light brown in color and situated near the Rio Grande.
