Huge, recently discovered B.C. cave closed to public and trespassers face $1M fine

B.C.'s provincial government has closed the area around a newly discovered cave thought to be Canada's largest for the sake of its preservation and public safety threatening a $1-million fine for those who don't stay away.

A helicopter crew came across the cavern in the northeastern corner of Wells Gray Provincial Park in March.It's the largest known caveof its type, with a depth about the length of a soccer field, and researchers have kept itsexact location a secret.

B.C. Parksannounced on Wednesday that the cave and its surrounding area are now closed to the public. Those who try to get close despite the shutdown face a fine of up to$1 million or a year in prison.

Geologist Catherine Hickson, who'spart of the team studying the cavern,said the closure came as a welcome surprise.

"You're kidding. Wow," she said Wednesday morning.

"It is an extremely dangerous location the cave itself and its remoteness."

'Not the place for a casual visitor'

Hickson first visited the site in September.

The entrance pitis about 100 metres long and 60 metres wide. Its depth is hard to measure because ofmist from a waterfall pouring over the opening, butinitial examsshow the cavernis at least 135 metres deep.

"For city-dwellers, when they're looking down into an excavation pit going down a few storeysfor, say, a parking garage multiply that 10 times and that's what you're looking into," she said.

"And, of course, there's no fences," she added.

The cave is about the size of a soccer field and might be the largest ever found in Canada.

Hicksonalso said only the most experienced hiker would be able to reach the cave safely, let alone climb into it.

"This is not a place for the casual visitor," she said.

"This would only be undertaken by the most serious people and even then, they're not going to be able to carry the equipment you need to carry into the cave,"Hicksonsaid.

In the winter, it'd be a 50-kilometre ski trip through unmapped terrain to reach the pit. In the summer, it would be a lengthy paddle and a gruelling hike with no support along the way.

Run into trouble and you'd needa monstrous,costly rescue operation to get home.

On top of thatdanger, there's also the chance the cave holds cultural significancefor First Nations in B.C.

"Certainly, it might have been a known location in terms of a sacred place but we just don't know," Hicksonsaid. "That's what [B.C.] Parks is working on."

The people who first spotted thecavefrom the helicopter named itSarlacc'sPitbecause of its similarity to the lair of thesarlacc, a creature fromStar Wars: Return of the Jedi.

Thecaveis the largest known example of the type known as"stripedkarst,'' which is marble interspersed with other types of ancient ocean rock.

Hickson said aformal naming of thecavewill happen after consultations with First Nations. She added further investigations and research of thecaveand its unique geography will likely be carried out in 2020, depending on funding.

B.C. Parks said the area will be closed until consultation with First Nations is finished and public safety has been fully assessed.

In the meantime, Hickson said Canadians should be content to appreciate the site from a distance.

"It's an important landmark an important feature for Canadians to be proud about," she said.
