Bob Rutherford, president of the Northern B.C. Caving Club, will begin exploring a large limestone formation near Atlin, on the Taku River, along with eight others from the club.
The group scoped out the area last year and based on the elevation, Rutherford estimates the cave could be up to 1,000 metres deep.
He is packing about 600 meters of rope, but if he finds what he's looking for, he doesn't think it will be enough.
"I don't think we have enough time, and possibly not enough rope to get to the bottom of it."
In addition to reams of rope, the expedition requires lots of cash.
"We're looking at between $1,500 to $2,000 per person to get in there."
The cavers will likely have to brave cold, dark, damp and dangerous conditions.
"A little bit of fear's a healthy thing, I think," Rutherford said.Suggest a correction
