This hike through a slot canyon was a great experience.  It was wonderful to feel enclosed with high canyon walls on either side.  At times, I had to scramble down rock formations to continue onward.  There was only the sound of the crunching of sand and gravel beneath my hiking boots.  The sun was getting close to setting, the temperature was cooler in the shadows, and around each new corner was a surprise.  Every few steps was a grand photo opportunity.  🙂
