The Argentiere Glacier descends from the heights of the Mt. Blanc massive below the Aguille or "needle" of Argentiere.   Part of the Alps, these beautiful mountains and canyons display some very cool geology.  From very old to young, and sedimentary to metamorphic to igneous in origin, these rocks have risen from the collision of two continents and been eroded by glaciers into deep valleys and high cliffs.  Though retreating to the higher altitudes, glaciers still fill the tops of most canyons here.
