Join AAron Capouellez of PA Woods and Forests for a twilight frog walk at the St. Xavier Nature Preserve in Latrobe.  The wetlands and riparian slopes of Monastery Run in this preserve host many native amphibians, and spring is when you can hear them best.  This guided walk will be slow-paced, but will involve walking through some wet areas. Please wear sturdy waterproof shoes and bring a flashlight or headlamp.
