Sediments from the Deseado River Near Puerto Deseado, Argentina47.7S 65.8W
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.
