BC is 950K km^2 with less than 5M people (drop Metro Vancouver and it's 2.5M). So 1.5 the size of France, the majority of which basically looks like Wells Gray (though Wells Gray has some extra beautiful spots). There are dozens of "Wells Gray like" parks, and most visitors don't hike up the mountains (and surely not off trails). So it's missable in theory.

[EDIT]: also mentioned in another cover - explorers believe cave was snow covered year-round up until 20-50 ago.

From the 2.5m remaining after you have subtracted Vancouver and the Fraser valley, now subtract the populations of nanaimo, Victoria, Kamloops, Kelowna, Nelson, osoyoos, Whistler, Campbell River, Prince George, fort St John, nelson and just about every other town that is big enough to have a few bank branches... The remaining rural area outside of any city limits is REALLY sparsely populated.

All this is true, but this is right outside Valemount and near Jasper National Park and in an area where there is a whole bunch of hiking, backcountry nordic and alpine heli-skiing and snowmobile tourism. It's not really the most remote part of B.C. Highway 16 isn't even that far away.

Are there any satellite imaging surveys or aerial surveys 50+ years ago that can confirm the assertion that the cave entrance has been covered with snow 100% of the time before 50 years ago?

We have photos of Robson and the glacier in jasper banph corridor, both are really close. And it was not “an assertion” but rather a conjecture.

You think people comb through satellite photos to look for cave entrances?

[assblaster]

I was only asking what the basis was for the assertion that the cave entrance has been persistently covered with snow year-round prior to 50 years ago.
