To the southeast is a distinct group of boulders, which are less than 15 ft long. They appear to be bedrock that is shattered in situ.

One of two processes, both involving periglacial processes, explains the formation of boulder fields, such as the Hickory Run boulder field. First, boulder-size blocks are generated from the fracturing of an upslope bedrock outcrop by alternating freeze and thaw. As boulders accumulate at the base of the rock slope, periglacial ice-catalyzed heaving and sliding transports them downslope during cold climatic
