North Dakota

In North Dakota, work has stopped on one section of the controversial Dakota Access Pipeline. Still, over the weekend protesters continued to stream into camps set up near the construction site.

One protest camp is about an hour's drive south of Bismarck. A prairie there is covered with tepees, tents and RVs. Flags from tribes around the country line the dirt road into the camp.

A remarkable transformation is underway in western North Dakota, where an oil boom is changing the state's fortunes and leaving once-sleepy towns bursting at the seams. In a series of stories, NPR is exploring the economic, social and environmental demands of this modern-day gold rush.

North Dakota's oil boom isn't just about oil; a lot of natural gas comes out of the ground at the same time. But there's a problem with that: The state doesn't have the pipelines needed to transport all of that gas to market. There's also no place to store it.

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."
