All Plateaus and Highlands (World)

This group collects the 19 Landforms subcategory members that the atlas already places under its own Plateaus and Highlands subcategory, the whole real-world population the atlas covers there. It is a single flat group, not split further by region or country, because Plateaus and Highlands stays well under the atlas's own hundred-member threshold for a further split. It sits directly under the Plateaus and Highlands subcategory and under the atlas's own Groups category, giving a reader a direct browse path from either the Plateaus and Highlands subcategory page or the Groups index.
