Don't let winter keep you cooped up! Join GSWA naturalist, Ginger Van Ryzin, for a refreshing 3-mile winter hike at the scenic Buttermilk Falls Natural Area in Mendham. We'll explore restored vernal ponds, follow India Brook, discover remnants of the old Mendham Water Company, and—weather permitting—witness the beauty of frozen waterfalls. Dress warmly, bring water, and wear sturdy hiking boots for this invigorating outdoor adventure. GSWA members $5, non-members $15. Registration is required.
