Lake Powell, United States
The Four Corners region is celebrated for its uniquely diverse geography that’s a visible memento of billions of years. For centuries, these deep canyons and towering plateaus hosted the native Navajo and Hopi tribes; snoop around a cave here and spy 1,000-year-old stone tools and rock art. Footprints and fossils reveal that this was a land where dinosaurs roamed; today you’ll recognise this striking scenery from the movies. Sweeping through this sprawling desertscape is Lake Powell, created in 1957 by the damming of the Colorado River. Adventurers can follow in the footsteps of Civil War veteran and one-armed explorer John Wesley Powell – he led the first successful scientific expedition down the Colorado River through to the Grand Canyon, and the area is named in his honour.
