The Rocky Mountain goat, bighorn sheep and dall sheep paddocks are all set on rocky, grassy hillsides and are perfect for such high-altitude mammals. This section of the zoo (Canadian Wilds) is the largest part of the Calgary Zoo, and for the most part all of the enclosures are above average.
This fake rock is done extremely well, it's just the expanse of it at the back of the enclosure which is a bit offensive aesthetically. I wonder if it still looks this good almost two decades later?
