Clay Cliffs of Omarama
The Clay Cliffs are tall pinnacles and ridges with deep, narrow ravines separating them. The cliffs are made of layers of gravel and silt, deposited by rivers flowing from the glaciers that existed 1-2 million years ago. Compared to the nearby mountains, which are 250 million years old, the Clay Cliffs are relatively new. Today the gravel and silt layers can be seen as sloping bands as the strata have been tilted since their deposit 1-2 million years ago.
