However, the rocks exposed in the canyon walls date back much further, providing a window into Earth’s distant past. The story of the Grand Canyon is one of the planet’s most profound geological narratives, a visible timeline etched into stone that invites contemplation of deep time.

As the plateau rose, the river maintained its course, aggressively downcutting through the rock layers. Chemical Weathering: Dissolution of minerals within the rock by slightly acidic water, weakening the structure.
Freeze-Thaw Weathering: Water seeping into cracks freezing and expanding, breaking off rock fragments. Periods of increased flow, triggered by climate changes or shifts in river tributaries, would accelerate the carving process, leading to the deep, steep-sided gorge seen today.

The formation can be broadly divided into the creation of the Colorado Plateau and the subsequent incision of the canyon by the river. The region was not always the arid desert it is today.
