Landscape The park consists of a deeply dissected Hawkesbury sandstone plateau, part of the
Woronora Plateau The creek gorges include Heathcote Creek, a tributary of the
Georges River. The sandstone was formed 200 million years ago, and periods of uplift began about 94 million years ago. Each period of uplift caused stream erosion, which cut more deeply into the plateau surface. Heathcote Creek cascades down a number of rock pools and small waterfalls to the Woronora River at the northern end of the park.
Flora The ridges and drier slopes are covered in forest dominated by
angophoras and
eucalypts such as bloodwood, grey gum,
Sydney peppermint, and scribbly gum. Grass-trees are common. Low heath growth consists of shrubs, including ti trees,
banksias, hakeas, and waxflowers.
Gymea lilies and forest oaks grow on the moister slopes. Blackbutts and
grevilleas grow in the Heathcote Creek Valley.
Fauna Sugar gliders,
ring tail possums, and possibly
eastern pygmy possums inhabit both Mirang Creek and Minda Gully.
Swamp wallabies are also present.
Honeyeaters are often seen, as well as
superb lyrebirds. Fish, eels and crayfish are commonly found in the creeks. ==See also==
