The exhibit would be about 1/2-1/3 of an acre in size, and includes this rocky backdrop running across the length of the exhbit, and between that and the visitor viewing is an array of himalayan planting, sleeping logs and a stream sourced by a waterfall in the 'cliff'. I'd personally give it a 10/10. This photo gives a good idea of what most of the enclosure looks like.
I agree - this is an excellent enclosure. My photograph only shows one end of it and doesn't do it justice at all. I would say this is probably the best snow leopard enclosure I have seen.
