Wilderness Vagabond Trip Report
The Grand Canyon sees millions of visitors every year. Its 227 mile length contains some of the most overwhelming views on the planet. Most sightseeing is done from the overlooks spaced out along the South Rim. For those taking the trip down into the canyon depths to the Colorado River below, all will pass by hundreds of distinct rock layers laid down millions of years ago. The powerful Colorado River has been slicing away at the rock for eons, carving out a few inches every thousand years. Here, a descent into the canyon is essentially a trip back in time. Some of the oldest metamorphic rock (Vishnu Schists), found in Granite Gorge, date back 1.7 billion years.
