They call it a phenomenon of some sort and I was surprised that I did not know about this sooner than I did.  After living in Peru for over a year you get to a point where you feel pretty knowledgeable on what is around, and certainly what is worth seeing.  I did not know about Tres Cruces or the awe-inspiring sunrise that I was in store for.  It was a bit of an adventure in and of itself just to get there.  Located a little over 4 hours outside of Cusco, journeying to this site is an adrenaline rush all on its own.  The road structures are still a bit unsteady with one-way roads that are not completely paved.  I survived by closing my eyes through most of the ride, and kept my focus on the sunrise that I knew was at the end of this treacherous road.
