I’m still in Australia at the moment but will be home in a few days. I’m looking forward to writing up a few blog posts about some geological sights in Australia once I’m back home. For now, though, here’s a picture showing another beautiful example of sandstone in the Sydney area. This picture was taken at the Sydney Zoo. The red and orange colors are a result of iron oxidation. The white is sandstone that lacks a color change from iron oxidation. Some bedding is also visible in this sandstone outcrop.
