Barrier River

The Barrier River is a river in the Mount Aspiring National Park in northern Southland, New Zealand. It is a tributary of the Pyke River, which it enters about 1 km south of Lake Wilmot. The Barrier River is fed by three glaciers and ice fields:
 * Demon Gap Icefall (North Branch)
 * Silver Glacier (via Silver Stream, between the branches)
 * Barrier Ice Stream (South Branch)
