  • How Glaciers Carved El Capitan and Half Dome

    How Glaciers Carved El Capitan and Half Dome
    2026/09/24
    Yosemite Valley's broad U-shaped canyon, its sheer granite walls, and Half Dome's missing half are all products of glacial carving, not river erosion. We cover how ice up to 4,000 feet thick reshaped the valley, why El Capitan and Half Dome survived as solid granite monoliths, and how a vanished glacial lake left behind the valley's famously flat meadows.
