We will take a Road Trip to see a few stops from the Volcanic History of Northern NJ begins in the Late Triassic period, about 200 million years ago. These mountains formed as a result of volcanic activity associated with the rifting of the supercontinent Pangaea. As North America began to separate from Africa, magma pushed up through the Earth's crust, creating the distinctive basalt ridges that characterize the area today. You will discover a landscape dominated by basalt, an igneous rock from the area's volcanic origins. This is contrasted sharply by layers of sedimentary rocks, such as sandstone and conglomerates, which tell tales of ancient rivers and lakes that once dotted the landscape. Voclanic origin mountains are known for their striking series of ridges and valleys, running roughly northeast to southwest. These formations provide stunning vistas and are a favorite among hikers and nature enthusiasts.
