This 100-acre wildlife preserve was obtained by the City of Saco in 2007 under the Land for Saco's Future program. The sanctuary comprises a diverse confluence of ecological habitats including upland softwood and hardwood forest, marsh, stream, vernal pools, bog, and evidence of a pre-historic landslide. Five well-marked trails wind through the property's mixed woodland forest and provide views of Stackpole Creek.
In 2021, a geologist at Maine Geological Survey discovered evidence of a large landslide from the 15th century. The geologist used LIDAR and carbon dating of soil core samples to determine that the landslide blocked Stackpole Creek 500-600 years ago and transformed the area's topography and environment. Eventually, Stackpole Creek cut a path through the landslide creating the sand and gravel streambed and banks that can be seen from the Blue Heron Trail and Beaver Path
