Also on Saturday, the official death toll of victims identified by the medical examiner increased by one, to 18, said Jason Biermann, program manager at the Snohomish County Department of Emergency Management.
Authorities have said they have recovered more than two dozen bodies — including one on Saturday — but they aren't added to the official tally until a formal identification is made.
And, underscoring the difficulty of identifying those killed in one of the deadliest landslides in U.S. history, Biermann said crews are not always discovering complete remains.
"Rescuers are not always making full recoveries," he said. "Often, they are making partial recoveries."
Personal items, both large and small, are also discovered in wreckage.
"What we found out here is everything from pictures to gun safes," said Snohomish County Fire District 1 battalion chief Steve Mason.
The items that would later be cleaned, sorted and hopefully returned to families.
All work on the debris field halted briefly Saturday for a moment of silence to honor those lost. Gov. Jay Inslee had asked people across Washington to pause at 10:37 a.m., the time the huge slide struck on March 22.
"People all over stopped work — all searchers — in honor of that moment," Mason said.
An American flag had been run up a tree and then down to half-staff at the debris site, he said.
Dan Rankin, mayor of the nearby logging town of Darrington, said the community had been "changed forevermore."
"It's going to take a long time to heal, and the likelihood is we will probably never be whole," he said.
Among the dozens of missing are Adam Farnes and his mother, Julie.
"He was a giant man with a giant laugh," Kellie Howe said of Farnes. Howe became friends with him when he moved to the area from Alaska. She said Adam Farnes was the kind of guy who would come into your house and help you do the dishes.
Adam Farnes also played the banjo, drums and bass guitar, she said, and had worked as a telephone lineman and a 911 dispatcher.
