The tense encounter occurred inside an Arctic Pipe Inspection yard at Prudhoe Bay, where the momma bear and her cubs are fairly well known to employees.
When you work at a remote oil field in Alaska, it pays to be bear aware.
The tense situation lasted about a minute.
The Alaska Department of Fish and Game told the employee that the sow and her cubs routinely feed in area dumpsters.
The employee shown watching from the yellow loader vehicle told FTW Outdoors that the sow was aggressive because had temporarily lost sight of her other cub.
Another employee captured the footage from the safety of the shop.
In the accompanying footage, an oil-field employee is shown scurrying onto the cab of a truck to escape an aggressive grizzly bear and one of her two cubs.
