This is Kudzu, it was introduced to the US to help prevent soil erosion, which it does very well, unfortunately it has no predators in the US. It is difficult to contain or remove and is slowly swallowing up the south eastern states.
It is also difficult to capture the scope of it in a photo.
Also, also, I apologize for the photoshop sky. We had the white, hazy skies of death that morning and I was in an area I rarely go but I had to try to grab some decent shots of this hillside.
