Mount Pleasant Caldera
![](https://en.wikipedia.org/wiki/Special:FilePath/Mount_Pleasant_Caldera_magnetic_mapping.jpg?width=300)
The Mount Pleasant Caldera is a large eroded Late Devonian volcanic caldera complex, located in the northern Appalachian Mountains of southwestern New Brunswick, Canada. It is one of few noticeable pre-Cenozoic calderas, and its formation is associated to a period of crustal thinning that followed the Acadian orogeny in the northern Appalachian Mountains.It sits relatively near to the coastline.
