Thunder Creek Falls

Thunder Creek Falls is a waterfall in Mount Aspiring National Park, Westland District, New Zealand. It is located in the Haast River valley, around 52 km inland from Haast, near the Gates of Haast bridge on State Highway 6. The falls are about 28 m high and the base is at an elevation of around 120 m where it flows into the Haast River.

The waterfall is the outlet of Thunder Creek, draining from a hanging valley created by erosion caused by the former Haast glacier and the Haast River. Over a period of around 14,000 years, the Haast River has formed a canyon, eroding the bedrock down by approximately the 28 m height of the falls.
