Highlands of Iceland – the interior plateau of Iceland; not a desert by climate, but effectively one because precipitation penetrates the volcanic soil so quickly that the land is infertile (20,000 km2)
Arctic Desert – the second largest "desert" in the world, though it consists of frozen ocean, land ice, and tundra, so (like the rest of this section) not a desert climate in any conventional sense
Some geographical features are referred to as "deserts", and this word may even feature in their names, despite not meeting any meteorological definitions for a desert.[citation needed]
