Crew finds 150-ton boulder likely left by glacier
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 (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.
