Geology of the Hudson Valley

Join our resident geologist, Kim Fendrich, on a journey through time. Learn about the geologic history of this area and observe evidence of tectonic activity, glaciation, weathering, and erosion throughout the Buttermilk Hill area of the Preserve.

With 4 sites of interest and a route that covers about 6 miles, we’ll be doing lots of walking so please come prepared with plenty of water and a light snack. Be prepared to move at a steady pace, some hiking experience is recommended.

Leashed dogs are welcome. Wear sun protection and comfortable closed-toed shoes. Long pants tucked into your socks are recommended to prevent exposure to ticks and poison ivy.

Suggested for ages 16+.

Meet in the Union Church parking lot at the end closest to the Pocantico Hills Fire Department. We’ll hike into the Preserve from here.

In the event of rain, the hike may be postponed; you will be notified via email at least 2 hours in advance.

Max: 20 people
