A helicopter team counting caribou in British Columbia, Canada, recently made an unexpected discovery during an aerial survey: Crew members spied an opening to a massive cave that had never been seen before and which might be the largest cave in the country.
Found in April in an alpine valley in Wells Gray Provincial Park, the cave's mouth gapes 328 feet across — if the Statue of Liberty were tipped over on its side, it would just about span the opening. The width of the cave is similarly impressive, measuring 197 feet, and the cave extends at least 443 feet straight down, the Canadian Broadcasting Corporation reported.
