Some slot canyons develop with more than one narrow section.  Antelope or Corkscrew canyon has gained note for both Upper and Lower canyons which remain among the most accessible and beautiful slot canyons.  These remarkable, narrows developed along a natural seam in the Navajo Sandstone to drain an immense slick-rock area and funnel runoff through the confined depths.  The resulting labyrinth of overlying wings and undulating canyon walls create ribbon-like passages and surreal cathedral high rooms of filtered and glowing light. 

Antelope Canyon flows into the deep of Glen Canyon which now holds Lake Powell.  Originally, Glen Canyon became known as a particularly beautiful gorge cut by the powerful Colorado River.  This great river has served to carry the silt cut by all the tributaries within the drainage of much of the western slope of the Rocky Mountains and slick-rock dominated Colorado Plateau.
