Boulder Field – Hickory Run State Park

The most notable feature of Hickory Run State Park is the huge boulder field located in the northeast corner of the park.The boulder field was created about 20,000 years ago during the most recent glacial period. The boulders consist of the sandstone and conglomerates identical to those capping the ridges that surround the field on three sides (the Mississippian Pocono Formation). Large amounts of melting waters from the glaciers apparently carried the boulders down from the ridges and into the valley where they now reside. The Boulder Field is truly a stunning sight, seemingly appearing out of nowhere in the park’s dense woodland. Many visitors cannot resist hopping from boulder to boulder across the field.
