Speculation abounds the mammoth tusk found at a South Lake Union construction site is a remnant of a prehistoric tunneling project. This would take a lot of pressure off a contemporary cousin, that white elephant Bertha.
Modern digital analysis — finger pointing between the contractor and government agencies — lays the blame on a big steel pipe or a rock that did not come up in earlier chats. Tsk, tsk.
Now it is tusk, tusk, and the speculation is over stalactites and stalagmites that were not present in the cave drawings plotting the path of the Ice Age project. Apparently paleo-communication skill sets have not dramatically improved in 15,000 years. That is the time frame assigned to the South Lake Union discovery.
So far that seems like a woolly estimate of when Bertha will be moving again.
