We just don’t know until right before it happens!!Join us for an evening of frog and salamander stalking, led by Jim Wilson and Brad Kunsman around the Minsi Lake/Bear Swamp area. We will visit vernal pools, watch salamanders on the move, and learn about the lives and habitats of our local amphibian friends. Here’s how this will work: we’ll collect the contact information of everyone who who would like to come. Jim and Brad will watch the weather and when they identify what they think is the right night, we’ll send out and email about the time and place to meet. The time will be after dark, which, of course, gets gradually later as the winter moves along. If you can make it, perfect!! If not, well then perhaps we’ll try again in 2022! Wear appropriate clothing – after all, it will still be winter, and likely it will be raining. It will definitely be dark.

Experience the winter woodlands at Northampton County Parks Department’s newest open space acquisition and learn about the history and mystery of the site’s famous Hexenkopf Rock

Join us for a guided walk led by Jim Wilson on this 77-acre tract of mature woodlands and wetlands on Hexenkopf Ridge in the beautiful Pennsylvania Highlands. Hexenkopf Rock—or simply Hexenkopf—is the centerpiece of the preserve. Hexenkopf means Witch’s Head in German and in the 18th and 19th centuries, Hexenkopf gained a reputation as a repository of evil and a residence of demons and witches, where pow-wow doctors would cast human illnesses from their sick patients. We’ll join Hexenkopf historians Linda and Ned Heindel at this infamous rock to hear about its folklore and legend. 1.5 hours long, about ½-mile in total length, starting at 11 am on 02/21. Inclement weather date February 28th.

Join the WCLV and the Little Lehigh Watershed Stewards for a guided walk on this private property to see beautifully built stone walls, cairns and other features believed to be part of a larger ceremonial landscape. Though their exact purpose or who built them is unknown, luminescence dating has provided a reliable date of construction of 2570 years ago. This represents the first time this technique has been used to directly date stone used in the construction of possible ancient cairns and walls in the Northeast. Enjoy a moderately easy walk across 14 acres of woodlands, on and off trail, with one short, but moderately steep hillside. 1.5 hours long, about ½-mile in total length, starting at 11 am on 01/24.
