Boulder Canyon

Boulder Canyon stretches along the Colorado River between Arizona and Nevada with steep rock walls and natural formations. The gorge was shaped by water erosion over extended periods and reveals the geological layers that make up the region's structure.

The canyon played a vital role during Hoover Dam construction in the 1930s as a natural transportation corridor. The gorge was intensively used to move materials and workers between construction sites during this period.

Boulder Canyon served as a crucial passage and water source for the region's original inhabitants. Local tribal communities used the gorge across generations as a natural connection between their settlement areas.

The canyon is accessible year-round through several entry points in both counties and requires different levels of preparation depending on the route chosen. Visitors should note that the area is remote and it is advisable to bring sufficient water and supplies.

The canyon walls display mineral deposits and rock layers from millions of years of Earth history. These visible strata tell the story of the geological development of the American Southwest in ways that reveal the passage of deep time.
