Learn about the geologic history of this area and observe evidence of tectonic activity, glaciation, weathering, and erosion throughout the Preserve. We’ll begin with a demonstration to put Earth’s 4.5 billion year history into perspective, followed by discussion and then a short hike to get up-close and personal with some rocks along the Sleepy Hollow trail. We’ll walk about 2 miles in total.
Meet in the Visitor’s Center courtyard. Please wear sun protection and bring water to drink.
Rain date: TBD.
