Marty,
This is the only one I know of:
I'm hoping my friend Alan can find something new to put this to "bed".
We know this photo is real early since Stanley had not yet come back to do the bunker renovations after finishing Banff Springs
What we don't know is whether this is the first year - or sometime in between the renovation and opening - which would mean that the hole could have already been altered.
If pressed to make a decision with what I know so far - I think the bunkers were there and the story is a wonderful tall tale.
But the thread does make you wonder a little...
