I was Overwhelmed by this canyon. corny as it sounds, there just aren't words to describe its enormousness and beauty. I went in winter, and it was freezing cold; there was snow covering the entire canyon (though I hear it was 10 degrees Celsius warmer at the bottom of the canyon). Though the canyon has been developed, it is so majestic, it seems that nothing can ruin the experience. This is definitely one of the seven wonders of the world, and visit to this site is amazing.
