The Deseado River flows across the arid steppes of Santa Cruz province, in southern Argentine Patagonia. The river appears whitish tan, in contrast with the surrounding light brown landscape.

The river empties into the Atlantic Ocean by Puerto Deseado, after a course of approximately 380 miles (610 km) across the province. Greenish sediments can be seen along the shoreline by its mouth.

Upon opening the full image, a pale tan horizontal line can be seen crossing the landscape and the offshore sediments, going over the coast just north of Puerto Deseado. This line appears to be composed of dust, or could possibly be smoke although the former seems more probable due to the tan color. Its origin is a spot by a plateau south and west of a bend in the river.

The Deseado River in southern Argentina appears as a whitish line cutting across the brown Patagonian terrain in the lower portion of this image. The river rises in Buenos Aires Lake in the Andes of southern Chile and Argentina. It flows generally eastward and southeastward through Santa Cruz province.

Near Koluel Kayke and Jaramillo it sometimes disappears into the dry soils of Patagonia, but it reemerges and empties into the Atlantic at Puerto Deseado. The total length of the Deseado is approximately 380 miles (610 km). It is used for irrigation along its lower course.

Upon opening the full image, many plateaus are visible inland, in the province of Santa Cruz. The terrain near the shore is flatter and criss-crossed by roads that appear as straight, light tan lines.

Greenish sediments spill past Puerto Deseado, originally called Port Desire, a city of about 15,000 inhabitants and a fishing port in Patagonia. The city is located in the Santa Cruz Province of Argentina, on the estuary of the Deseado River.

The Deseado River is born from the glacier-thaw Buenos Aires Lake on the northwestern part of the province at the Andes range, and travels for 615 km before reaching the Atlantic Coast. On its way southeast, its water is tapped for irrigation.

The river sometimes disappears under the arid terrain, to re-emerge before reaching Puerto Deseado on Santa Cruz’s coastline, where it produces a deep-water natural port.

Santa Cruz is a province of Argentina, located in the southern part of the country, in Patagonia. It borders Chubut province to the north, and Chile to the west and south. To the east is the Atlantic Ocean. It is the second largest province of the country, but the least densely populated of the Argentine mainland.

The average temperatures are 13°C in summer, and 3° in winter, when temperatures can fall to -25°. Strong winds blow all year round.

To the west, the Andes at these latitudes are lower than in the centre and north of Argentina, but still have year-round snow. An immense ice sheet feeds numerous glaciers. Even though precipitation in this western ice-sheet area is common, rain is scarce in other areas, with an average of 200 mm per year.

The lakes in western Santa Cruz province are mostly fed by glacieal melt-water; however, due to the cold climate their shores are not used for agriculture. The largest include Buenos Aires Lake (2,240 km², of which 881 km² is in Argentina), Cardiel Lake (460 km²), Viedma Lake (1082 km²), Argentino Lake (1560 km²), Pueyrredón Lake, Belgrano Lake and San Martín Lake (1.013 km²) are all in the west of the province.

The Atlantic coastline is a mixture of beaches and cliffs. From the centre to the Atlantic coast in the east, plateaux of descending height dominate the landscape. The cold, arid steppe is crossed by rivers that produce fertile valleys; Deseado River, Santa Cruz River, Gallegos River, Coyle River, Chico River and Pinturas River.

Here, the Deseado River can be seen crossing the upper half of the image horizontally and spilling greenish sediments into the Atlantic Ocean. Its source is the glacier-thaw of Buenos Aires Lake, visible as a large, dark blue body of water due west of the river along the mountainous border with Chile.

Further down the shoreline, the Santa Cruz and Chico Rivers create a large delta from which more sediments flow into the ocean. The source of the Santa Cruz Rivers begins at the shore of the Viedma and Argentino Lakes (both visible although partially covered by clouds west of the delta.
