Monday Geology Picture: Weathered Sandstone at Cottage Point, Australia

Posted by Evelyn Mervine

Weathered sandstone exposure at Cottage Point, Australia.

Here’s another picture from my recent trip to Australia. This picture shows a weathered  sandstone outcrop that I saw (by kayak!) at a place called Cottage Point. You can see fresh banded sandstone (light in color) underneath a darker weathering rim. Weathering has created some very interesting shapes in this outcrop!

There are quite a few sandstone rocks in the Sydney area. They are frequently used as building stones — for example, the ones I shared in an earlier post.
