There are 3 main layers of rock in Golden Gate Highlands National Park, the characteristics of which have lead to the famous cliff formations present in the park today. The red layer was created 200 million years ago when swampy rivers deposited the mud-like sediment. 196 million years ago, the area dried up and became a desert, resulting in the yellow sandstone deposits. From 160-190 million years ago, volcanic activity capped the area with a basalt layer. The rivers and streams in the park have carved the rocks into their present formations. The name ’Golden Gate’ originates from the two cliffs that face each other on either side of the road: at sunset, the yellow sandstone becomes a rich gold colour. And those black marks?All around the park you can see black stripes on the rock, even long after it has rained. These are areas where water seeps out of the rocks. Minerals from the top basalt layer (manganese dioxide) are carried in the water and these stain the rocks black. The water enables organisms like algae and moss to live on the rock as well.
