Wild horses in the landscape

My sister and her husband live outside Reno.  Wild horses regularly pass across the land.  She thinks this one is outcast, ostracized by the herd, but he is stunning to me.  
This alludes to an old painting which I cannot put a finger to now.   Contrails, arching through the blue, blue sky, become trails.  The sky is vast above a low mountain landscape.  The desert terrain is so different, I am overwhelmed.
