Located in a gully, this locality consists of outcropping hydrothermally-altered and weathered Wooltana volcanics containing veins and pockets of zeolites, calcite and crystallised ilmenite. Fibrous and splintery actinolite is abundant. Stilbite is present as both cream-white and deep orange clusters of crystals, and the locality has produced the best zeolite specimens in South Australia.
For many years an opaque, white, radiating zeolite infilling stilbite-lined vughs was identified as pectolite (e.g. in Coats and Blissett 1971) or mesolite, however, analysis of the mineral by Dr. Allan Pring in 1987 confirmed the species as scolecite (Australian Mineralogist, Vol.2, No. 2. pg. 34).
