The Olivine Ice Plateau is a glacier in the Olivine Wilderness Area [1] and Aspiring National Park in New Zealand's South Island. [2] The plateau is named after the mineral olivine, which is common within the Dun Mountain ophiolite that underlies the area. [3] The plateau extents to the west over the Forgotten River Col. into the Forgotten River and to the north it merges with the Andy Glacier, which feeds a tributary of the Arawhata River. [4] The Olivine Ice Plateau is one of many glaciers in the region of the Arawhata, Dart / Te Awa Whakatipu, Hollyford / Whakatipu Kā Tuka and Matukituki rivers' headwaters. [5]
The area was explored and mapped in the 1930s by J.T. Holloway. [6] [3] In the 2010s the glacier has retreated, leading to a more rocky approach to the plateau over the Forgotten River Col. [7] The plateau is "revered" by New Zealand trampers for its remote and challenging location. [7] [8] [9] [10] [11]
Fiordland, is a non-administrative geographical region of New Zealand in the south-western corner of the South Island, comprising the western third of Southland. Most of Fiordland is dominated by the steep sides of the snow-capped Southern Alps, deep lakes, and its steep, glacier-carved and now ocean-flooded western valleys. The name "Fiordland" derives from an alternate spelling of the Scandinavian word for steep glacial valleys, "fjord". The geographic area of Fiordland is dominated by, and roughly coterminous with, Fiordland National Park, New Zealand's largest national park.
Fiordland National Park is a national park in the south-west corner of South Island of New Zealand. It is the largest of the 13 national parks in New Zealand, with an area covering 12,607 km2 (4,868 sq mi), and a major part of the Te Wāhipounamu a UNESCO World Heritage Site established in 1990. The park is administered by the Department of Conservation. The southern ranges of the Southern Alps cover most of Fiordland National Park, combined with the deep glacier-carved valleys.
Arthur's Pass National Park is located in the South Island of New Zealand and covers 1,185 km2 of mostly mountainous terrain. Adjacent to it lies Craigieburn Forest Park. The park is administered by the Department of Conservation.
Mount Aspiring National Park is in the Southern Alps of the South Island of New Zealand, north of Fiordland National Park, situated in Otago and Westland regions. The park forms part of the Te Wahipounamu World Heritage Site.
Mount Aspiring / Tititea is New Zealand's 23rd-highest mountain. The peak's altitude of 3,033 metres (9,951 ft) makes it the country's highest outside the Aoraki / Mount Cook region.
Lake Wakatipu is an inland lake in the South Island of New Zealand. It is in the southwest corner of the Otago region, near its boundary with Southland. Lake Wakatipu comes from the original Māori name Whakatipu wai-māori.
The Dart River flows through rugged forested country in the southwestern South Island of New Zealand. Partly in Mount Aspiring National Park, it flows south-west and then south for 60 kilometres (37 mi) from its headwaters in the Southern Alps and the Dart Glacier, eventually flowing into the northern end of Lake Wakatipu near Glenorchy.
The Hollyford River / Whakatipu Kā Tuka is in the southwest of the South Island of New Zealand. It runs for 72 kilometres (45 mi) through Fiordland, its sources being close to the Homer Tunnel and in Gertrude Valley in the southern Darran Mountains.
The Hollyford Track is a tramping track in New Zealand. Located at the northern edge of Fiordland, in the southwestern South Island, it is unusual among Fiordland's major tracks in that it is largely flat and accessible year-round. It follows the Hollyford River which in turn follows the course of the Hollyford Valley.
Lake Alabaster / Wāwāhi Waka, also known by the Māori name of Waiwahuika, lies at the northern end of Fiordland, in the southwest of New Zealand's South Island. The lake runs from northeast to southwest, is five kilometres (3.1 mi), and covers seven km2 (2.7 sq mi).
An ice field is a mass of interconnected valley glaciers on a mountain mass with protruding rock ridges or summits. They are often found in the colder climates and higher altitudes of the world where there is sufficient precipitation for them to form. The higher peaks of the underlying mountain rock that protrude through the icefields are known as nunataks. Ice fields are larger than alpine glaciers, but smaller than ice caps and ice sheets. The topography of ice fields is determined by the shape of the surrounding landforms, while ice caps have their own forms overriding underlying shapes.
Lake Marian is an alpine lake at the southern end of the Darran Mountains in the Fiordland National Park in the South Island of New Zealand. The lake is located just above the treeline in a hanging valley leading northwest from the Hollyford Valley near The Divide pass. The valley is sheltered by steep snow-covered peaks of over 2,000 metres (6,600 ft) on all sides apart from the entrance.
David John Gunn was a New Zealander and promoter of the Hollyford Track. A farmer and bushman, he ran his almost wild cattle in the glacier-cut Hollyford Valley in Fiordland, South Westland, New Zealand.
The Forgotten River is located in northern Fiordland, New Zealand in Mount Aspiring National Park, and is a tributary of the Olivine River. The Forgotten River starts at the Forgotten River Col at the western edge of the Olivine Ice Plateau in the Five Finger Range. It flows south-westward to join the Olivine River as a hanging valley south of Four Brothers Pass.
The Haast-Hollyford road or Haast-Hollyford Highway is a long-standing proposal to link Haast via the Hollyford Valley to Milford Sound and Te Anau in the South Island of New Zealand. Proposals for this road have been mooted since the 1880s.
Charles Edward Douglas was a New Zealand surveyor and explorer, who came to be known as Mr. Explorer Douglas, owing to his extensive explorations of the West Coast of New Zealand and his work for the New Zealand Survey Department. He was awarded the Royal Geographical Society Gill Memorial Prize in 1897.
The Humboldt Mountains or Humboldt Range are one of the many ranges which make up the Southern Alps / Kā Tiritiri o te Moana in the South Island of New Zealand. They lie to the northwest of Lake Wakatipu in the Otago Region. Parts of the range lie within Fiordland National Park, and they form the southern extremity of Mount Aspiring National Park. The range was named by early explorer James McKerrow, and like many geographic features worldwide, it was named in honour of notable scientist Alexander von Humboldt.
Martins Bay is an indentation in the southwest coast of New Zealand's South Island. It lies immediately to the south of Big Bay and some 30 kilometres north of the mouth of Milford Sound at the northern tip of Fiordland. The Hollyford River reaches the Tasman Sea at Martins Bay.
Mount Alfred is a hill in Otago, New Zealand, that was formed by glaciers during the last ice age. It is the prominent hill due north from Glenorchy located between the Dart River / Te Awa Whakatipu and Rees River located in the Queenstown-Lakes District.
The Garden of Eden Ice Plateau is a large ice field on the western side of New Zealand's Southern Alps / Kā Tiritiri o te Moana. At over 9 km (5.6 mi) long, the Garden of Eden is one of the largest ice fields in New Zealand, along with the equally-sized Garden of Allah Ice Field which sits just to the north. The ice field is one of many geographic features in the area between the main divide of the Southern Alps and the Adams Range which share biblical names, a convention first established by the earliest explorers to the area. The Garden's remote location and difficult conditions make research difficult, especially with restrictions on helicopter landings imposed through the designation of the area as Adams Wilderness Area in 2003. Despite this, the ice plateau has been a popular destination for tramping groups for over 80 years, with access routes from both coasts and easily reachable areas once on the plateau itself.
