Hiking out of the Grand Canyon — 8 miles, 5,000 feet — felt like re-emerging from a quiet haven inside the earth to stand again atop the soil of civilization. Back up here it's a hot and crowded mess. Everything feels excessive. Everyone seems oblivious. The chaos is distinct after having been so deeply peaceful and disconnected. It feels like I’ve been gone for months, yet it's only been seven days. 

We saw so much in those 90 miles rafting downstream.
