Boulder halts garage dig
Builder might give millennia-old, 150-ton rock to city
EVERETT – Workers digging an underground garage for a new hotel in Everett 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 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, said it may give the boulder to the city to try to find it a home.
