I emerged at last, stumbled a few steps in the mud and then I saw it: an ethereal mountain emerging from a tossing sea of clouds framed between two dark barracksöa massive, blue-black tooth of sheer rock inlaid with azure glaciers, austere yet floating fairy-like on the near horizon. It was the first17,000-foot peak I had ever seen. I stood gazing until the vision disappeared among the shifting cloud banks. For hours afterwards I remained spell-bound. I had definitely fallen in love.

  In Memoriam A.H.H., canto 31.

Man, her last work, who seemed so fair, Such splendid purpose in his eyes, Who rolled the psalm to wintry skies, Who built him fanes of fruitless prayer, Who trusted God was love indeed And love Creation's final lawö Though Nature, red in tooth and claw With ravine, shrieked against his creed.

-Tennyson
