More on the fracking front:
Two years ago, the photographer Tony Bynum, whose images of Big Sky country have graced the covers of magazines like Field and Stream, embarked on a different type of photodocumentary project. His goal was to create an interactive map to illustrate the oil and gas boom in his own backyard on the eastern edge of Glacier National Park in Montana.
Mr. Bynum hired a pilot and conducted aerial flights to map the drill pads, oil wells, pumps and power lines that snake along the Rocky Mountain Front there. He said he was seeking to “get the word out that one of America’s most pristine ecosystems is on the cusp of becoming industrialized.”
