Don’t be left out in the cold this January, join GSWA education associate Dan Ross as he leads a winter hike through Buttermilk Falls Natural Area in Mendham. You will get a chance to check out the remnants of what was once the Mendham Water Company, and abandoned relics from the area’s iron ore mining past. Along the way we will also keep our eyes peeled for woodland creatures prepping for the long cold months ahead! Registration required. Register online or by calling 973-538-3500.
