Which Argentine cold desert is also called the Patagonian Steppe?

The Argentine cold desert also called the Patagonian Steppe is the Patagonian Desert.

The Patagonian Desert occupies much of eastern and southern Patagonia, primarily in Argentina, between the Andes and the Atlantic coast. It is commonly called the Patagonian Steppe because its dry landscape is dominated by low shrubs, bunch grasses, gravel plains and open plateaus rather than extensive sand dunes.

This is a cold winter desert. The Andes block moisture carried inland by prevailing westerly winds, creating a powerful rain-shadow effect. The region is also influenced by the cold Falkland Current along the Atlantic coast. Temperatures are generally cool, frost is common, and snow remains limited because the air is so dry.

The desert formed as the Andes rose during the Miocene, roughly 14–12 million years ago. Despite its harsh conditions, it supports guanacos, rheas, pumas, foxes and other wildlife. Sheep ranching became especially important after European settlement, while oil, gas and coal extraction are also significant in parts of Patagonia.
