About this site

Of the sixteen vernal pools we monitor in the park, this is one of the larger pools. Located near the campground entrance and with Lakeside / Mason-Dixon Trail passing by, it is also one of the most accessible. This pool catches drainage flowing down from East Camping Area Road, and works as a filter to purify the runoff.  

Photos from the 1970s show this area was a mixture of thick hedgerows and old fields/  pastureland. This pool may have originally been a borrrow pit, or dug out to create a watering hole for livestock.  The habitat has changed dramatically over the past 50 years as trees have grow up around it. 

Photos submitted to Chronolog help us document how this wetland continues to change over time, as volunteers work to remove invasives and lightly thin the canopy around the pool to allow light in to encourage the plants that grow in the basin like swamp milkweed and water plantain. Learn more about seasonal wetlands at Vernal Pools of Pennsylvania, and learn more about wetland restoration in this Vernal Pool Wetland Restoration Webinar.
