Evelyn at Georneys had a fine idea: A geo-picture a day. It's day three, Wednesday, and our subject of the day is one of America's crown jewels. It is immediately recognizable to most people: Grand Canyon National Park in Arizona.
There is no place like the Grand Canyon. It is such an intricate and precious piece of earth art that I never get tired of the view, and I cherish every chance to visit, every opportunity to hike in its depths. So much geology is laid bare in this place: the rocks exposed in the canyon walls, the existence of the canyon itself, the myriad caverns that grace some of the limestone layers. It's a virtual candy store for geologists.
