Edna Bette-Jean Masters may be gone, but she's never been forgotten.
On July 3, 1960, at the age of 21 months, Bette-Jean disappeared while playing outside with other children near Red Lake, 45 kilometres northwest of Kamloops.
Last August, RCMP reopened the case with a public appeal for any information.
And on Saturday, Kamloops Search and Rescue will join several other volunteer agencies to comb the area with the faint hope of finding clues.
Cattle ranching and forestry work has disturbed the ground there over the past decade or so, said Alan Hobler, Kamloops search manager.
"So it's possible something that had been buried or hidden from view has gotten exposed recently," he said.
In August, investigators said they planned to use new technology, such as DNA examination and software that digitally ages photographs, in an effort to generate new leads in the case.
Abduction has long been suspected since nothing was found in initial searches despite the fact that Bette-Jean was carrying items that should've been dropped if she'd gotten lost.
An unfamiliar 1959 Chevrolet car with Alberta plates was seen nearby with a man and woman in their late 20s. The car had either "cat eye" or "bat wing" taillights, the RCMP said.
Investigators have never been able to determine the identities of the couple or whether they were connected to Bette-Jean's disappearance.
Search and rescue teams from Shuswap, Logan Lake, Nicola Valley and South Cariboo hope that a shoulder-to-shoulder walk through the area on Saturday may reveal something.
Thirty-five or more rescuers are providing their services entirely free and are even paying their own gas to get to the location.
"A child of that age, it tugs at everybody's heartstrings," said Hobler.
The search also gives organizations the opportunity to provide training for recruit volunteers, said Hobler. And it allows them to help with a tragedy that has never been solved.
"This thing is completely a mystery. There's no hints at what could've happened, it's just a lot of theories. I think that intrigues people," said Hobler.
The case was closed in early 1963. However Bette-Jean could still be alive today, say police, and would now be 55 years old.
She had curly blonde hair, blue eyes and a fair complexion, was wearing a green bonnet, a pink T-shirt and faded overalls at the time. She had an oval-shaped burn scar on her left arm, which investigators believe would still be there today.
