Egg Rock
Facts and practical information
Egg Rock is an outcrop of Silurian Straw Hollow Diorite at the confluence of the Assabet and Sudbury rivers, where they form the Concord River in Concord, Massachusetts. The outcrop is located on a roughly oval intermittent island of about 100 by 50 meters. Egg Rock is usually accessible using foot trails over land, but during high river levels the island is separated from the mainland by a narrow channel. The highest point of Egg Rock is about 39 meters above mean sea level and about 6 meters above normal river level. ()
