These older photos are good for nostalgia's sake, but can often leave one guessing as to what the current facility consists of. For instance, what now stands in place of this now "demolished" exhibit?
To my knowledge the Ibex Rock was demolished to make way for the new Great Bear Wilderness as I think the name is. I think it is to open this spring, in April or May, and will have Polar Bear, Grizzly and American Bald Eagle.
