Which Afghan desert's name is commonly translated as Desert of Death?

The Afghan desert commonly translated as Desert of Death is Dasht-e Margo.

Dasht-e Margo is a desert region in southern Afghanistan, mainly across Nimruz and Helmand provinces. Its name comes from Dari Persian: dasht means “plain” or “open land,” while margo means “death,” producing the familiar translation “Desert of Death.”

The landscape consists largely of rocky and clay-rich plains, salt-encrusted areas called solonchaks, cracked mud surfaces known as takirs, and only occasional oases. The desert lies near two other arid regions, Dasht-e Khash and the Registan Desert, which can make maps and quiz questions about southern Afghanistan confusing.

Dasht-e Margo is not the same as the Registan Desert, despite both being major Afghan deserts. Registan means “sandy place” and is associated more directly with extensive sand-dune terrain, whereas Dasht-e Margo is identified by its Dari name and its location across the country's southwestern desert belt.
