(Dickinson Press) Workers digging the foundation for downtown Fargo's Block 9 high-rise pulled what appeared to be an enormous rock out of the ground earlier this week.
Any excavation is bound to turn up a few rocks, but this one was about the size of a skid loader.
The Kilbourne Group, one of the developers of the 18-story building, consulted with a geologist, and the firm's staff was excited to think that the rock might be a memento from the days of the wooly mammoth.
Adrienne Olson, a Kilbourne spokeswoman, said by email on Tuesday, Oct. 9, she heard if that were the case, it would be the largest "dropstone" found in what used to be glacial Lake Agassiz.
