Forestry roading material quarry in highly weathered teschenite and basalt, and part of a large and techtonically uplifted seamount. Teschenite is the key matrix rock, with all other minerals being secondary. Remains of several volcanic pipes have been found.
Various sceptres of quartz and calcite can be found at the micro level in this location, including unusual dipyramidal quartz diamonds. This is a privately owned forest with no public access. Collecting as per arranged field trips of the Wellington mineral and rock club.
(Wellman 1970) describes it as a circular teschenite intrusion in the Brocken Range suggesting it is possibly an eroded volcanic plug. He states attractive hand specimens of agate and quartz after calcite can be commonly found in the Kaiwhata Stream.
(Hutton, 1942) studied in detail several rocks from Red Hill, collected shortly before by D.A. Brown. Species described include a diopsidic type of clinopyroxene and augite; sheaf like aggregates of colourless thomsonite as sharp acicular needles, associated with minor natrolite; an amorphous green-blue to rusty brown hydrated silicate of magnesium and iron infilling amygdales; plagioclase with intrusions of apatite, biotite, and hematite; irregular aggregates of bowlingite; sphene with no details; analcime plentiful in thin sections; abundant ilmentite-hematite; pale yellow apatite needles, and calcite.
Quartz and pale amethyst crystals can be found in the Little Kaiwhata Stream that drains Red Mountain. The crystals are surrounded by a white to pale pink material, changing to an orange colour in acid, suggested as either calcite or more likely dolomite. Red coloured heulandite, manganese oxides, greenockite, and celadonite are also noted as found.
