Are there sand dune deserts in Argentina?

Yes, Argentina has sand dune deserts, most notably the Campo de Medanos in the province of San Juan. This region features large sand dunes formed by wind action over time. Additionally, the country hosts various arid and semi-arid regions that resemble desert environments, such as the Patagonian Desert, which, while not entirely comprised of sand dunes, contains areas with significant dune formations. These landscapes are characterized by sparse vegetation, dramatic temperature changes, and minimal rainfall, contributing to their desert-like characteristics. The diversity of Argentina’s geography allows for the presence of such unique desert ecosystems.
