This is an incredibly fascinating exhibit, with well-worn pathways on the vertical terrain. Is there a shelter somewhere...or perhaps a hoofstock house of some kind? Would any buildings be hidden from public view?
@snowleopard: There's indoor accommodation next to the viewing area. The use of existing landforms is effective and it's a very pleasant corner of the zoo, but perhaps not as stunning as some of the photos suggest. Prague, for instance, has much more dramatic ungulate exhibits.
