YELLOWSTONE, Mt (FOX44) - A 25 mile long oil slick is moving along Montana's Yellowstone River.
Tens of thousands of gallons of crude oil spilled into the river Saturday when an ExxonMobil pipeline broke.
Although the ruptured pipeline was shut off in roughly six minutes, the damage has already been done.
Oil from the pipeline covers some pasture land, and area farmers say they have now lost the summer feed for their livestock.
Exxon execs have apologized for their mess, and say they're doing their best to soak all the oil up with stuff like Boom.
Crews can't use boats because the river is too dangerous right now.
It's not yet clear how extensive the damage is.
