Geology hint for part 2: You two were wandering around on the extreme western edge of the Colorado Plateau (think layer cake geology like in Grand Canyon) at or very near where the Basin and Range geologic province begins. Imagine the west end of the 3 day old lovely layer cake falling off the edge of its' serving platter and spilling onto someone's plate filled with fresh from the oven sliced turkey and mashed potatoes covered in hot gravy.
What a great description.
