What is volcano in maryland?

There are no active or dormant volcanoes in Maryland. The state's landscape is dominated by rolling hills, valleys, and forests, but there are several ancient rock formations, including cliffs and ridges, that were formed by tectonic activity and erosion. The most notable geological feature in Maryland is the Chesapeake Bay, which was created when a meteorite struck the Earth about 35 million years ago. The Bay is also home to several small islands that were formed by volcanic activity millions of years ago, but there are no active volcanoes in the state.
