Fernie cave continues to break records as the largest in Canada
A 24-member team led by Katie Graham also connected a new entrance and extended the cave’s northern limit, researchers said.
Led by Golden resident Katie Graham, an exploration team mapped the Bisaro Anima cave near Fernie to 10.5 kilometers in length and 690 meters in depth, confirming it remains Canada's deepest cave.
A 24-member team explored the cave during a two-week expedition beginning in September, connecting a new entrance and extending the cave's northern limit to reveal new passages.
Previously measured at 682 meters, the cave's expansion surprised researchers; Graham added, "We got a new entrance that connects down into the cave."
Exploring the site presents logistical hurdles as the team navigates wet, cold conditions; Graham noted the group requires additional scuba tanks to extend exploration further.
With 120 meters remaining until the water exit, the team plans to return next year to gather more data as Graham expressed excitement that the cave continues to grow annually.
