In a wide view over Sheep Canyon, BNSF’s Cowley turn out of Greybull, Wyoming, snakes through through the spectacular abyss on the hot (100°F) afternoon of June 23, 2016. Two recently reactivated EMD SD70MACs power the southbound train that is tracing the Bighorn River at milepost 414 just south of Spence on BNSF’s Casper Subdivision.
