A newly discovered cave in a remote valley in British ColumbiaB次元官网网址檚 Wells Gray Provincial Park might just be the countryB次元官网网址檚 largest.
The feature was spotted by a helicopter crew from the provinceB次元官网网址檚 Ministry of Environment and Climate Change in March, when they were conducting a caribou census through the northeastern part of the park.
Geologist Catherine Hickson, who first went to the cave in September, said the discovery promises a dramatic new chapter in the story of Canadian cave exploration.
B次元官网网址淚t was absolutely amazing,B次元官网网址� she said. B次元官网网址淚 immediately recognized that this was very significant.B次元官网网址�
Before making the trip, Hickson and fellow researchers including John Pollack, a cave expert, spent months studying satellite imagery and rocks in the area, she said.
The entrance pit to the cave is about 100 metres long and 60 metres wide, and while its depth is hard to measure because of the mist from a waterfall, initial examinations show it is at least 135 metres deep.
B次元官网网址淚tB次元官网网址檚 about the size of a soccer field,B次元官网网址� Hickson said. B次元官网网址淪o, if you think of a soccer field and you put that soccer field on its end so you have this pit going down. Think about this giant circular or oval hole that just goes down and down and down. It is truly amazing.B次元官网网址�

The cave is the largest known of its type, a variety of B次元官网网址渟triped karst,B次元官网网址� which is marble interspersed with other types of ancient ocean rock, she said.
B次元官网网址淚tB次元官网网址檚 in an area where this size of a cave is unusual,B次元官网网址� she said. B次元官网网址淚tB次元官网网址檚 an important landmark B次元官网网址� an important feature for Canadians to be proud about.B次元官网网址�
The people who first spotted the cave from the helicopter named it SarlaccB次元官网网址檚 Pit, because of its similarity to the lair of Sarlacc, a creature from B次元官网网址淪tar Wars: Return of the Jedi.B次元官网网址�
But a formal naming of the cave will happen after consultations with First Nations, she said.
The feature was formed underneath glaciers for potentially tens of thousands of years, so there is no way of knowing the real age of the cave right away, Hickson said.
B次元官网网址淩ight now, because of the recession of the glaciers, it is open to the sky,B次元官网网址� she said, adding that as ice retreats from the landscape due to climate change, more such features might be discovered.
Caves support a very unique ecosystem because they are dark so the flora and fauna living in such areas are acclimatized to those conditions, Hickson said.
With this cave, the flowing water is at such a rapid rate that it may not allow many creatures to call the area home but further research is needed, she said.
Although the cave is in a remote, rugged valley covered with snow and ice for a greater part of the year, Hickson said researchers are keeping the exact location a secret so as to preserve the unique area.

Hickson said further investigations and research of the cave and its unique geography will likely be carried out in 2020, depending on funding.
B次元官网网址淲e think everything is known and everything has been discovered, but hereB次元官网网址檚 a major discovery that is made in todayB次元官网网址檚 world and likely has never been seen before and certainly not explored before,B次元官网网址� she said.
B次元官网网址淚tB次元官网网址檚 just a message that there is still stuff out there yet to do and yet to be discovered.B次元官网网址�
