The junction of the Arnold and Grey rivers, known as Kotukuwhakaoho, was an important site of battles for
Ngāi Tahu, as it was the location where
Ngāti Wairangi was defeated in the late 18th century, and later
Ngāti Tūmatakōkiri in the 1810s. The miners who died in the
Brunner Mine Disaster on 26 March 1896 were buried in the cemetery at Stillwater. Thirty three men were buried in a mass grave. Hundreds of people came by train from towns on the West Coast to attend the funerals. In 1906 the town's industry was centred on saw milling. It had a hotel, store, post and telegraph office and a school which opened in 1888. In 2015 the hotel was still in operation but has since closed. == Sawmilling ==
