EVERETT, Wash. (AP) Workers digging an underground garage for a new hotel in Everett, Washington, recently struck something big about 30 feet below the surface.
This week they uncovered it - a boulder that's thousands of years old and bigger than an SUV, weighing an estimated 150 tons.
A geotechnical engineer who was called out to examine it, Kurt Merriman, told The Daily Herald (http://bit.ly/1yXICvv ) it's a glacial erratic - a giant rock left behind by a glacier maybe 18,000 years ago.
The site superintendent for the Halvorson Construction Group, Ben Hansen, says it may give the boulder to the city to try to find it a home.
