The Inland Kaikoura Range is a mountain range in the northeast of the South Island of New Zealand .
geography
The Inland Kaikoura Range lies in a southwest-northeast orientation between the rivers Dillon River in the southwest and Awatere River in the northwest, the Waima River in the northeast and Clarence River in the southeast and the southwest half in the Marlborough District and half in the northeast half in the Kaikoura District of Canterbury Region and the Marlborough District . The district boundary runs here on the ridge of the mountain range. The Inland Kaikoura Range has a length of around 90 km, with the individual mountain ridges and valleys mostly oriented transversely to the longitudinal axis of the mountain range. The width varies between 12 km and up to 16 km.
The highest mountain in the Inland Kaikoura Range is the Tapuae-o-Uenuku with a height of 2885 m . A total of eight other mountain peaks are above the 2000 mark, listed from southwest to northeast, the Dillon Cone with 2173 m , the Saint Bernhard with 2256 m , Mount Major with 2269 m , Mount Union with 2295 m , Mount Symons with 2408 m , Miter Peak with 2621 m , Mount Alarm with 2877 m and Crows Nest with 2449 m .
On the southwest flank of the Inland Kaikoura Range , in addition to the Gloster River , Tweed River and Bluff River, numerous streams flow into the Clarence River , not big enough to be named. On the northwest side of the Awatere River , in addition to numerous streams, the rivers, Dane River , Kowhai River , Tone River , George River , Winterton River , Hodder River , Jordan River and Medway River flow directly or as a tributary into the Awatere River .
geology
The base rock of the north of Canterbury and the east of the Marlborough District , in which the two mountain ranges Inland Kaikoura Range and Seaward Kaikoura Range are located, consists of hard sandstone and laminar dark sedimentary rock, the greywacke and mudstone , which are interspersed with strips of volcanic rock . This base rock comes from the Triassic and the Early Cretaceous and is therefore between around 100 and 250 million years old. The rock is covered with younger sedimentary rock, including strips of coal layers , quartz sands , limestone , maritime mudstone , which would be translated into German as claystone, and gravelly mixtures. The age of the cap rock is between 1 and 85 million years.
The Inland Kaikoura Range is criss-crossed by geological faults . The folding of the rock and the resulting mountain formation has removed parts of the cover rock through erosion and exposed the base rock in the rugged, towering rocks. The cover rock can still be seen on the flanks of the mountain range.
Some faults in the Inland Kaikoura Range are known, others are suspected. The best-known fault here is the Clarence Fault , which extends along the mountain range on the southeast side, in the lower slopes. Another known fault in the area is the Awatere Fault , which extends northeast in the valley of the Awatere River on the southeast flank of the opposite mountain range.
Protected areas
A small part of the Inland Kaikoura Range (part of the northeast flank) was bought by the Forest Heritage Fund in 1993 together with the Seaward Kaikoura Range and placed under protection in 2008 as Ka Whata Tu o Rakihouia Conservation Park . The park has since been administered by the Department of Conservation . The park has a size of 881 km 2 .
