Location: Shotover River, South Island, New Zealand
North of Queenstown, on New Zealand's South Island, is the Shotover River. The Shotovover is a fast-flowing river famous these days for water sports such as white-water rafting and jet boat rides. In earlier days, the Shotover was known as a rich source of gold, and we understand there was quite a gold-mining boom in the area in the 19th century.
Yes, the water really is that pale turquoise color. The source of the river is in the island's Southern Alps, and the color of the water (we were told) is due to minerals and tiny ice crystals in the water from the melting glaciers that feed the river.
