Zion National Park Professional Review and Guide
"The rugged, lush and narrow canyon with a sometimes raging river and spectacularly colored rocky promontories characterize Zion Canyon, which has been compared by many to the Valley of Yosemite. The sheer rock walls are indeed similar, but those at Zion have far more color. The canyon road extends eight miles through canyons, past buttes and mesas, interspersed with vegetation. Zion’s mountains are famous for their color– brownish-red at the bottom, becoming whiter as they rise toward the sky.
Then, too, there are fantastic shades of purple and lilac, all the more brilliant when captured in the sunlight. The fanciful names of many of the park’s features probably owe their origin to early Mormon settlers. But when you see the dramatic formations that gave rise to these names, you will fully understand the awe that must have been felt by these early visitors. This eTrail explains in detail how to tour the park. In addition to a park map the details include driving tours, outdoor recreation, accommodations, campgrounds, dining, and more."
