See anomalous stone constructions believed to have been built by Native Americans and learn about their possible meaning.

Join the the Perkiomen Watershed Conservancy and the Watershed Coalition of the Lehigh Valley for a guided walkabout co-led by Jim Wilson with the WCLV and John Martin, Ceremonial Landscape Council Director for the Lenape Nation of Pennsylvania. Jim will point out emerging signs of springtime, while John will address what the anomalous stone constructions found at Manderfield and throughout the woodlands of this reach of the Perkiomen Creek Watershed may mean to Native Americans. Relatively easy, but occasionally rocky and sometimes wet half-mile long trail walk suitable for all skill levels. Starts at 10:00 am on March 27; inclement weather date the next day, Sunday, March 28. Parking location and further guided walk details in confirmation email.
