Annapolis Harbor & Thomas Point, Maryland
Annapolis & the Severn River
The Severn River opens into the Chesapeake, with Annapolis Harbor and Thomas Point in one portrait.
The chart follows the Severn past Annapolis and Eastport into the open Chesapeake. Harbor entrance lights mark the smaller waterways, while Thomas Point Shoal Light flashes red to the south. A portrait frame brings the river, waterfront and bay approaches together.
