Millions of years ago, the granite block of Half Dome was larger, but there was never a matching half. Glaciers undercut it near the base, and slabs of rock fell away from a broad vertical crack in the granite, leaving a sheer face, while remnants of the missing rock still project from Half Dome's rim. This area has more granite domes than any other place in the world, and these massive domes form when large curved layers of rock exfoliate, or slab off. In an Anwahneechee tale, two travelers, Tissiak and her husband, Tokoyee, fought with each other; when he beat her and she hurled her basket of acorns at him, they were turned to stone for their wickedness. The acorn basket became Basket Dome beside Tokoyee, or North Dome, and the rock face of Tissiak, or Half Dome, is stained with her tears.
