"They told me also of the Wood and dark Mountains, of the Hill Difficulty, of the Lions, and also of the three Giants, Bloody-man, Maul and Slay-good." Pilgrim's Progress

This is an image of the hills just west of the Columbia river. Criss-crossing the country, so casually by air, I often wonder at the determination and courage it must have taken to do it on foot or with a horse-drawn wagon. These hills seem to me  like a monument to the terrible struggles those people went through.
