Zion Canyon is the main, central canyon of Zion National Park in southwestern Utah, known for its stunning, deep sandstone walls carved by the Virgin River. It's the park's most popular and accessible area, featuring iconic hikes like Angels Landing and the slot canyon The Narrows, with most visitors using a free shuttle to explore the Scenic Drive for much of the year.

Bryce Canyon National Park, a sprawling reserve in southern Utah, is known for crimson-colored hoodoos, which are spire-shaped rock formations.

Lake Powell was created by the flooding of Glen Canyon by the Glen Canyon Dam, which also led to the 1972 creation of Glen Canyon National Recreation Area, a popular summer destination of public land managed by the National Park Service. The reservoir is named for John Wesley Powell, a Civil War veteran who explored the river via three wooden boats in 1869. It lies primarily in southern Utah, with a small portion in northern Arizona.

The Glen Canyon Dam is a 710-foot-tall concrete arch dam on the Colorado River in Arizona, completed in 1963, which created Lake Powell to store water and generate hydroelectric power for the Southwestern US. The dam, a controversial project that submerged the natural beauty of Glen Canyon, provides vital water storage for the region's growing population and funding for environmental programs, though its operation has been impacted by drought and reduced water flows in the Colorado River.

Horseshoe Bend is a horseshoe-shaped incised meander of the Colorado River located near the town of Page, Arizona, United States. It is also referred to as the "east rim of the Grand Canyon." Horseshoe Bend is a superb example of an entrenched meander. Six million years ago, the region around Horseshoe Bend was much closer to sea level, and the Colorado River was a meandering river with a nearly level floodplain. Between six and five million years ago, the region began to be uplifted. This trapped the Colorado River in its bed, and the river rapidly cut downwards to produce Horseshoe Bend as we see it today.
