Inner Harbor in Baltimore, Maryland — The American Northeast (Mid-Atlantic)
Jones Falls
The Jones Falls River is an important tributary of the Patapsco River and the largest of several waterways that empty into Baltimore Harbor. From the time of its first colonial settlements, the Jones Falls River has served Baltimore City as a transportation corridor and a source or drinking water. The swift-flowing river also powered mills that played an integral role in propelling Baltimore into an industrial giant in the 1800s.
Mr. Trash Wheel
When it rains, rainwater flows toward the nearest body of water, carrying anything it pucks up with it- including trash and pollutants. This "runoff" flows into the Jones Falls and continues its journey into the Patapsco River, Chesapeake Bay and eventually the Atlantic Ocean. Mr. Trash Wheel helps combat this by collecting trash as the Jones Falls flows into the Patapsco River. Mr. Trash Wheel is one of a family of trash wheels that collect more than 1 million pounds of trash annually. To help make their easier, reduce the use of single-use plastics and ensure trash is properly disposed of so it doesn't "runoff" into local waterways.

For 133 years, the Seven Foot Knoll Lighthouse and its beacon provided a safe guide for sailors at the mouth of the Patapsco River, 12 miles downstream from Baltimore's Inner Harbor. First lit in 1856, the Seven Foot Knoll Lighthouse is the oldest screwpile lighthouse in Maryland and was in active use until its relocation to Baltimore's Pier 5 in 1988. The lighthouse was restored by Living Classrooms Foundation and has been designated a National Historic Landmark. It is not managed by Living Classroom Historic Ships in Baltimore.

The innovative design of screwpile lighthouses made them easier and faster to build because no underwater masonry foundation was needed. Instead, these lighthouses were suspended above the water by a system of cast-iron piling with corkscrew-like bases, which were screwed in the Bay floor.
