Hoodoos, earth pyramids and rock pillars produced by the differential erosion of rock layers of unequal hardness, leaving a standing pillar typically capped by a more resistant stone, following the hoodoo (fairy chimney) landform class of standard geomorphology. Includes classic capped hoodoos in badlands terrain (Drumheller Hoodoos, Thor's Hammer, Wahweap Hoodoos), earth pyramids of the same origin under regional names (Earth Pyramids of Ritten, Earth Pyramids of Platten), and named single-rock pinnacles and spires (Old Man of Storr, Duckbill). Belongs here: any standing rock column or pillar shaped by differential erosion of layered rock. Does not belong here: an isolated monolith of uniform crystalline or igneous rock not shaped by differential capping (this atlas's own Inselbergs and Crystalline Monoliths subcategory), or a karst limestone tower shaped by dissolution rather than differential erosion (Karst Caves and Sinkholes).
