“Over the span of 350 million years, rivers washed sand and pebbles into the area, layer-upon-layer, and the sand was ground finer and harder together until it formed sandstone rock. Strong winds and heavy rains have eroded the sandstone away to form the dome shapes we see today. The Bungle Bungle gain their tiger-stripes from black algae growth that permeates the more porous layers of the rock, and a glossy orange build up of manganese and iron staining." www.discoverwest.com.au
