The Monoliths (Manchester-by-the-Sea)

The Monoliths, also known as Agassiz Rock, is a 116-acre (47 ha) park in Manchester-by-the-Sea, Massachusetts, owned and maintained by The Trustees of Reservations.

The park's name is from two examples of large glacial erratic boulders plucked from bedrock.

[2] In 1874, a group of students named this site to honor Louis Agassiz, the Harvard University professor who first theorized that the rocks that dot New England's landscape were shaped and deposited by glaciers.

[1] Agassiz visited the site and found the erratic physical features fit his hypothesis.

Prior to Agassiz's hypothesis, it was widely believed that the scattering of rocks throughout New England were the result of Noah's flood.
