The Great Schuylkill to Susquehanna Passage – From the 1600s to Today’s Rail-Trail

Pennsylvania’s Schuylkill to Susquehanna Major Greenway, designated in 2021, was inspired by the Greenway’s Native American predecessor – the Great Minquas Trail. A 1926 plaque marks the trail where it crossed Ridley Creek in Rose Valley PA, noting that “thousands of beaver skins yearly were carried down to Dutch and Swedish settlers on the Delaware.”

A network of rail-trails that follows this passage will soon link Harrisburg to Philadelphia. The webinar above was presented by trail and preservation architect Bob Thomas on March 21, 2024. Bob has worked on developing many parts of this new greenway.

The Main Line of Public Works recording

The late 18th and early 19th century in America saw the great effort to connect the east coast across the Allegheny Mountains to the fertile Ohio River Valley. The competition between the area eastern financial centers of New York City, Philadelphia and Baltimore was intense. Fearing the success of New York State’s Erie Canal, in 1834 Pennsylvania opened a “Main Line of Public Works” – made up of a series of canals, inclined planes, and railroads – linking Philadelphia and Pittsburgh. The area we know today along the Main Line was part of this great achievement.

From our streets to our tap water: Consequences of road salt application in an increasingly paved world

Each year, over 20 million metric tons of road salt (e.g., sodium chloride) are applied to U.S. roadways as a de-icing agent. Much of this salt makes its way into our rivers and streams that serve as a source of drinking water by downstream municipalities. This talk will show how road salt application in southeastern Pennsylvania is impacting our local watersheds, drinking water infrastructure, and tap water. We will also explore how salt concentrations in streams are linked with the amount of impervious surfaces within the watershed, and evaluate potential solutions that might benefit our streams.

Dr. Steven Goldsmith is a watershed biogeochemist at Villanova University with over 20 years’ experience evaluating how anthropogenic practices impact streamwater quality. He has researched a wide array of streams from the tropics to Antarctica and is a regular collaborator with the Lower Merion Conservancy.

This event was hosted in partnership with the St. Joseph’s University Institute for Environmental Stewardship.
