The indigenous Ngāi Tahu people named this place Kura Tawhiti, treasure of a distant land. Later European settlers, reminded of towering battlements, called it Castle Hill. It is well named in either case. Situated on the spine of New Zealand's South Island, south of Arthur's Pass, Castle Hill is still a high-country sheep station. But amoeboid, stony marbles crisply framed against a steely blue sky, it is also an otherworldly karst landscape of tumbling limestone boulders and tors rising from the rolling, grassy turf.
