Everett workers find 150-ton boulder, left behind by a glacier
Workers digging the underground garage for a new hotel in Everett struck something big last week about 30 feet below the surface.
This week they had uncovered a boulder 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 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.
