Increased precipitation also allowed evergreen forests, in modern times limited to an elevation of 7,000 feet (2,100 m), to extend well into the canyon.(Price 1999, p. 42) Price, L. Greer (1999). Geology of the Grand Canyon. Grand Canyon, Arizona: Grand Canyon Association. ISBN0-938216-68-6.
The Grand Canyon region gently slopes southward, so water on the North Rim flows into the canyon and water on the South Rim tends to flow away. Tributary canyons are therefore larger north of Grand Canyon and smaller south of it. Grand Canyon Village on the South Rim is located 2 miles (3.2 km) from the Colorado River and 4,460 feet (1,360 m) above it while Bright Angel Point on the North Rim is located 7.75 miles (12.47 km) from the river and is 5,940 feet (1,810 m) above it.(Chronic 2004, p. 98) Chronic, Halka and Lucy (2004).

An exception is the slight effect that uplifts, upwarps and swells created by earlier phases of the Laramide orogeny have. For example, formations exposed on the South Rim are 800 feet (240 m) lower than the same formations on the North Rim because the North Rim is closer to the highest part of the Kaibab Uplift.(Foos 1999, p. 1) Foos, Annabelle (1999).
