Nice spot to look for cedars or ridges.
200 million years ago when the continent split apart. New Jersey dropped down as a Rift Valley into a shallow sea but was continually filled by the erosion of huge mountains to the west as the land continued to drop down it continued to fill up with more earth.
This formed sandstone which was compressed into shale as some areas were 3000 feet deep in shale
So sit at the shale rock and see if you can see the cedar trees on the ridge here
The first tree to grow up on the nearby field used to be cedars (cedar preserve duh) as birds spread the seeds (tiny pine cones actually) cedars make dense canopy and kill off the meadow until a few trees such as oak and hickory shade and kill off the cedars. This will happen again here unless the meadow is mowed or burner. Note the ditch around the meadow most likely a drainage ditch so the area could be farmed
Now in many suburban areas Calary pear trees an invasive from Asia are replacing cedars as the first tree to enter the medow with their pretty white blooms and torns (all geocaches love thorns, sorry none at GZ)
