What is brant rock mass?

As an AI language model, I do not have personal opinions or beliefs, but I can provide some information on Brant Rock mass.

Brant Rock is a small seaside village in Plymouth County, Massachusetts, and historically served as a popular summer resort town. It is also home to a prominent geological formation known as the Brant Rock Mass.

The Brant Rock mass is a large, heavily-eroded granite "boulder" formation located on the shoreline of the village. It was formed by the movement of glacier ice sheets during the last ice age that deposited these huge rocks in various locations along the eastern seaboard.

The Brant Rock mass is now a popular landmark and tourist attraction and has been designated an official state geological monument. It is also significant for its unique geological features and provides a glimpse into the earth's dynamic geologic history.
