Fox Glacier 5.92

Fox Glacier / Te Moeka o Tuawe is a 13km temperate maritime glacier located in Westland Tai Poutini National Park on the West Coast of New Zealand's South Island. It was named in 1872 after a visit by then Prime Minister of New Zealand Sir William Fox. Following the passage of the Ngai Tahu Claims Settlement Act 1998, the name of the glacier was officially altered to Fox Glacier / Te Moeka o Tuawe.GeographyFed by four alpine glaciers, Fox Glacier falls 2,600m on its 13 km journey from the Southern Alps down to the coast, with it having the distinction of being one of the few glaciers to end among lush rainforest only 300m above sea level. Although retreating throughout most of the last 100 years, it was advancing between 1985 and 2009. In 2006 the average rate of advance was about a metre a week. In January 2009, the terminal face of the glacier was still advancing and had vertical or overhanging faces which were continually collapsing. Since then there has been a significant retreat, with the 2009 high level clearly visible as vegetation line on the southern slope above what is left of the lower glacier today.The outflow of the glacier forms the Fox River. During the last ice age, its ice reached beyond the present coastline, and the glacier left behind many moraines during its retreat. Lake Matheson formed as a kettle lake within one of these.
