Valleys and Rift Systems (World)

This group collects the 16 Landforms subcategory members that the atlas already places under its own Valleys and Rift Systems subcategory, the whole real-world population the atlas covers there. It is a single flat group, not split further by region or country, because Valleys and Rift Systems stays well under the atlas's own hundred-member threshold for a further split. It sits directly under the Valleys and Rift Systems subcategory and under the atlas's own Groups category, giving a reader a direct browse path from either the Valleys and Rift Systems subcategory page or the Groups index.
