Can you guess where any of these are from? (And yes, one of them is very easy!)
The easy one is the Y-K Delta (5th one down). But, easy as in having experience reading aerials and having flown over the geological regions.
My geology (hard and soft) was from the TC Chamberlin building on Beloit College campus. There are two great US places to view geology in action– the arid southwest USA and the arid southwest Alaska.
