North Dakota

If you've seen any coverage of North Dakota's oil boom, you've seen the images — oil rigs, truck traffic, "man camps," miles of temporary housing.

But there is something about this place that just can't be captured by a still photograph. It's a feeling you get when you cruise down an endless highway under a vast, big sky — until suddenly: BOOM. You're wedged between semitrucks dwarfing what was once a quiet farm town.

A dozen oil tanker rail cars burst into flames after two trains collided in eastern North Dakota on Monday.

No one was hurt during the derailment or fire, but thick black smoke was rolling off the wreckage after five explosions rocked the town of Casselton, about 10 miles west of Fargo.

The collision occurred after a westbound train carrying soybeans derailed, and an eastbound train hauling crude oil ran into it, Cecily Fong, the public information officer with the North Dakota Department of Emergency Services, tells Reuters.

The handling of an oil spill in North Dakota is raising questions, after a state agency waited to tell the public it had taken place. A wheat farmer was the first to recognize the spill had happened; it became public knowledge nearly two weeks later.

Here's how the AP describes the spill's discovery:

"Farmer Steve Jensen says he smelled the crude for days before the tires on his combines were coated in it. At the apparent break in the Tesoro Corp.'s underground pipeline, the oil was 'spewing and bubbling 6 inches high,' he said in a telephone interview Thursday."
