‘I’ve never seen anything like this before,’ one official said. ‘And I don’t think these people here (have) either. The ice jam is amazing’
A huge 30-mile block of ice his causing chaos in an Alaskan town as water has been flowing onto the land.The colossal river ice jam, which is when water builds up behind a block of ice, was starting to rotate Wednesday as water finally chewed ice chunks away from the stubborn, frozen mass after most of the residents were forced to flee from the rising water.An aerial survey Wednesday afternoon revealed chunks of ice have broken off at the front of the 30-mile ice jam on the Yukon River, National Weather Service hydrologist Ed Plumb said.
That means the jam will move soon and waters will begin to recede in the waterlogged town of Galena, 20 miles upriver.
