Köppen climate type:
This area has a thick sequence of Paleogene basalts, with some highly vesicular zones in the lower parts (Sutherland and Bottrill, 2005).
The best known site is on the eastern side of the hill along the Mole Creek to Sheffield highway alongside a scenic lookout, and is the locality documented by Andersen (1984). It is here that vesicles many metres across have produced specimens with large chabazite- Ca crystals. Chabazite-Na as herschelite has also been reported from Gads Hill (Sutherland and Bottrill, 2005).
Two occurrences of note were reported by Andersen, one, a cavern measuring 8 metres by 3 metres by 1 metre, the second, 5 metres by 2 metres by 1 metre. Phillipsite, thomsonite and calcite occurred with the chabazite in these vesicles. Rare levyne was also recorded from this locality, the first reported occurrence of this mineral in Tasmania.
Other minerals recorded by Andersen include apophyllite, nontronite, tacharanite and tobermorite. It is still possible to collect specimens from the boulders on the eastern side of the road, but the area is quite overgrown and leeches are common.
