The George Stream, Miller Stream and Wharekiri Stream tributaries of the lower Clarence provide access to the northernmost part of range. The Miller Stream catchment contains some of the best remaining podocarp and beech forests of the Seaward Kaikouras.
The Clarence Valley has a long history of European occupation. Sheep stations were first established in the 1860s, but have always been difficult enterprises due to the rugged and dry land and poor access. Streams in the Clarence watershed are often deeply eroded, while elsewhere thick scrub and matagouri hampers progress. Only a few small pockets of beech and podocarp forest remain, and the climate is drier than on the eastern slopes of the Seaward Kaikouras. Many of the earliest ascents of Tapuae-o-Uenuku and Alarm were from the Clarence, but as the Awatere Valley opened up, the Hodder River approach became the usual access. Nevertheless, the Clarence approach has a unique remote charm and spectacular land forms.
