Limestone outcrops in Kaikoura

I got up this morning for a sunrise...but not a lot happening. Nor'west cloud had drifted across. The light was a little flat but quite liked this view across Kaikoura bay with the limestones rocks in the foreground.
Kaikoura Peninsula is made of limestone and siltstone laid down beneath the sea about 60 million years ago; it has been exposed to the elements for a mere 180,000 years. Once an island, it is now linked to the mainland by debris eroded from the Kaikoura mountains, These mountains are rising faster than any other mountains in New Zealand (10 mm per year) but erosion keeps their height fairly constant.
Periods of rapid uplift have formed the steep-sided promontories and have twisted the neatly layered limestone into unusual shapes. The relatively young rocks have been worn into many interesting forms by the pounding sea. In less active periods, the sea has cut large tidal platforms in the softer sandstone.
I was unable to upload yesterdays blip- very frustrating internet. Please check out my beautiful albatross here and some images of Kaikoura here
