The Fall Line - The Geology of Maryland Series

The rolling hills seen along I-70 are a characteristic feature of the Piedmont Plateau, one of Maryland’s six physiographic provinces. This centrally located region continues east from the Appalachians into the Coastal Plain. The area where the Piedmont and the Coastal Plain intersect is described as the Fall Line, and it can be traced on a map, marking the first set of falls that make the rivers impassable for boats. That's why major cities like DC, Baltimore, and Philly are all in a line, marking the fall line. This corridor is an important transportation route, with Interstate 95 as the perfect example.

Join us for a day trip to experience the geology of the Fall Line as seen from two Harford County locations. We’ll begin our geological adventure at Eden Mill Nature Center, where we'll set off on a hike to discuss the rock formations in the area, about one mile in total. After working up an appetite, we’ll head over to Broom’s Bloom Dairy for lunch and ice cream, then drive to Anita C. Leight Estuary for a second hike along the Vista Trail. We’ll check out the area down at the water to get a good look at the local geology along the riverbank, too. We’ll also bird and investigate any interesting flora or fauna we encounter while on the trail. The total trail length should be less than two miles. You are welcome to pack a lunch or purchase food at Broom’s Bloom. If time permits, we’ll meet the animal ambassadors at Anita C. Leight Estuary, too.

This field trip supports our newest exhibit at our building, The Geology of Maryland, to be open soon.
