Ground-penetrating radar, which helped to find the unmarked graves of 215 First Nations children at the site of a former residential school in Kamloops, B.C., is a technology that has been around for decades with several uses in both archeology and infrastructure maintenance.

TORONTO -- The discovery of 215 First Nations children buried in unmarked graves near a former residential school in Kamloops, B.C., has sent shockwaves through Canada.

“It’s a lot like a fish finder: it takes energy signals and it sends it through the surface of the earth and rebounds off different densities and comes back up,” Craig Campbell, owner of G3Tech, a non-destructive testing company in Saskatoon, told CTV Saskatoon.It’s also a similar technology to that used in ultrasound machines.

“When you dig a grave, the soil changes -- the composition changes, the density can change -- and the ground-penetrating radar can actually pick up that change.”In addition to archeology, GPR has several commercial uses, primarily to assess the structural integrity of infrastructure. “ expecting to find graves, because there’s multiple stories of these sites already taking place where they are and -- non-destructively -- we can go in there and pinpoint them so they can go through ceremonies and put up headstones,” said Campbell.

“We can’t just sit around, we’ve done enough of that,” Sxwithul'txw told CTV News Vancouver Island. “It’s been confirmed. There’s bodies all across the country at all of these sites I’m sure and sitting around and not doing anything is the last thing we should be doing.”

Needs to be on drones. It’s a bit more difficult but it can be done. Likely military has something working just fine, there are a lot more bodies out there than just in graveyards. The trick fo success is using automation and AI filtration.

Why didn’t Trudeau do this 3 years ago as he promised? What has he being doing for 3 years?

Robert Jago: Why accepting reality of residential school harms is necessaryIt is not possible to look at the unmarked graves of 215 children that were uncovered on the grounds of the former Kamloops Residential School and deny the… The past is the past. Let’s move on together Accepting reality and taking action to correct is needed. So is forgiveness on the side of those harmed. Both sides must move if real healing is to take place. Working together is the only way to move forward. Pierre Trudeau oversaw the residential school system for 15 years!!!!

'In your heart it hurts': A residential school survivor says she'd like the Pope to apologizeA survivor of a residential school in Ontario says the discovery of unmarked children's graves in Kamloops, B.C. brought back horrific memories of the treatment she endured as a child. Good news: 'Pope Benedict has said he is sorry for the physical and sexual abuse and 'deplorable' conduct at Catholic church-run Canadian residential schools.' Saying you're sorry shows empathy for a bad situation. Apologizing is admiting you caused the bad situation. That's the crux of it. we need to stand in solidarity we have our own church and keep our traditions alive
