Located south-west of Ingham, Mount Fox was created by a violent volcanic explosion about 100000 years ago. In the explosion, a lava flow 10 metres thick spewed from the southern end of the crater and chunks of molten magma were thrown out of the volcano's vent.
Today, the well formed crater, about 10 metres deep, is covered with sparse grasses and stunted trees amongst the eucalypt woodland environment. The pink and long-fruited bloodwoods are common in this area and vine thicket is found in a steep gully on the southern slopes.
Mount Fox's tussock grass slopes shelter a number of small animals. On a cool day in the winter months, skinks and other reptiles can be seen basking on the volcanic bombs. During the hot summer months, the grass provides protection from the sun and are ideal nesting places for ground-dwelling birds like the little button quail. After sunset, rufous bettongs (small wallaby-type mammals) emerge to feed on herbs and grasses. The large wing span of a wedge-tailed eagle can also be seen, as this bird of prey soars above the Mount Fox crater.
