Folks:
I've been following this thread with some interest. Regarding the origin of the toponym "Apple Pie Hill," I would posit that it's sudden rise on an otherwise relatively level terrain had the appearance of an eighteenth-century apple pie. The pies of that era, unlike those of today, contain a large heap of cut-up apple, creating a substantial mound that the baker then covered with dough. Prior to its insertion into the oven, I'm sure the pie's appearance, with its unbaked mounded crust, resembled what we know as Apple Pie Hill, even down to the crust's color matching the sand that composed the salient's structure.
Best regards,
Jerseyman
