Some of these were derived from frost-shattered bedrock that lies just beneath the bouldery mantle. Other boulders, based on their subrounded shape, have been glacially transported. For those who are more adventurous, the Steeny Kill Lake Trail provides a moderate hike down to the Steeny Kill Lake moraine, ending on the north shore of the lake. 0.0 mi/2.9 mi 0.1 mi/3.0 mi 0.4 mi/3.4 mi From Stop 6 parking area, exit and turn right.
