Tusk, believed to be mammoth's, found in South Lake Union
A tusk paleontologists believe came from an Ice Age mammoth was discovered while workers were digging at a construction site in South Lake Union Tuesday, according to the Burke Museum of Natural History and Culture.
The tusk was found on private property, so the landowner will decide what to do with it. A Transit Plumbing employee found the tusk while workers were excavating on a project, according to company President Jeff Estep.
