This group collects the Inselbergs and Crystalline Monoliths subcategory's members framed by their own description as steep, narrow granite peaks and spires, several noted for technical rock climbing or a sheer, near-vertical face: El Capitan, Half Dome's neighbors, Cerro Torre, Fitz Roy, Trango Towers, Trollveggen and the sharp needle peaks of Brazil's Serra dos Orgaos and Mantiqueira ranges. These are distinguished from this subcategory's dome and bornhardt group by a narrow, vertical profile rather than a rounded one, and several are named destinations in the history of big-wall and alpine climbing.
