The range is at the eastern extent of the Tasman Mountains which make up much of the island's northwest, making it easily visible from across the low-lying Waimea Plains further to the east. The range's location and its many uses make it a significant site for local Māori, including the iwi of Te Ātiawa and Ngāti Rārua. This includes the prominent peaks of Mount Arthur and Pukeone / Mount Campbell, which both hold mana in their own right and have become part of the identity of the aforementioned iwi.
