Jupiterimages/ Photos.com/ ThinkStock(LAUREL, Mont.) -- Exxon Mobil Corp. says damage caused by its oil pipeline leak into the Yellowstone River could go beyond the confines of the waterway.



An Exxon Mobil pipeline ruptured Friday night releasing tens of thousands of gallons of oil into the river. The pipeline typically transports 40,000 gallon barrels of oil each day.



Since the spill, the Texas based oil company reports more than 280 people are working to clean the contaminated area, a span which has extended miles from the original site. Cleanup crews faced extra obstacles this weekend as they worked in rough, high, and muddy water.



Montana Governor Brian Schweitzer is scheduled to survey the damage Tuesday.



Investigations into the cause of the leak are ongoing.
