Ecuadorean Sky (Boing Boing Flickr Pool)

Boing Boing reader Porter Yates shares this photo, titled "The Earth is Flat," with the Boing Boing Flickr Pool—and explains:

Looking onto Andean fields near Simiatug, Ecuador. My vantage point was from ~ 13,000 ft. The clouds filled the valley below as the sun began to set. I had never seen a sky quite like this.
