As we pass overhead the Grand Staircase-Escalante National Monument, we follow the Cottonwood Canyon southward toward Glen Canyon and the Grand Canyon at the horizon. Each canyon in its turn provides a boundary that limits or guides our perspective. To the observer on the ground, these great canyons are obstacles that must be circumnavigated. From our aerial perspective, while we may imagine the plight of the pioneer at meeting these obstacles, we see these canyons as something greater…they define boundaries of flowing pathways across the surface of the continent and act as guides to interpret the movement of water through the landscape created by flowing molten earth. Meandering through once mild ripples in the earth’s crust, the water’s movement grows more erratic and dramatic as it cuts deeper into the crust to reveal the soul of the landscape.
