During the Eocene, more of Zealandia was below sea level than at the present day.  During this time, submarine volcanoes were active along the present day coastal section of the Waitaki Whitestone Geopark.  

At Bridge Point a nearby, likely short-lived volcano erupted around 32 – 36 million years ago.  The volcano was subsequently eroded, creating an environment for marine life and accumulation of marine sediments.

 

Update 12 July 2023: Due to recent erosion, the carpark and beach access to the site has been compromised.

Please be aware the following hazards include: narrow, tides, wildlife, sharp and slippery rock underfoot, and falling debris from cliffs. Tsunami risk – if an earthquake is strong or long, get gone.
