A huge crop art image protesting the proposed Keystone XL pipeline covers an 80 acre corn field outstide of Neligh, Nebraska on April 12, 2014. The image, which lies on the proposed pipeline route that crosses the Ponca Trail of Tears, was created by the farmers, ranchers and Native American tribes of the Cowboy and Indian Alliance in collaboration with artist John Quigley.
