The Name All 300 Rivers and mountains challenge
Recall 150 rivers and 150 mountains or volcanoes from a fixed Wikidata snapshot, ranked by Wikipedia language coverage. Subclasses count; ranges, regions, standing water and features outside Earth do not. Exact names and reviewed forms such as Mount Everest or Everest, Amazon River or River Amazon, count together. Each place earns one point and a coordinate pin. The run ends at all 300 or when you choose to stop.
Each accepted place scores one point, and repeat answers never score twice. The run completes automatically when you reach 300.
