Sounds like a collective "meh", which surprises and disappoints me, but hey, that's why I asked. Ya narrow-minded so-and-so's.
DON'T LISTEN TO THE NAY SAYERS, TOM!
Your idea is one of the most original ideas since the a/b maps. It should be developed further.
As I mentioned above I can stand at the edge of the parking lot at our local GC clubhouse and see this:
Looking down always makes perspective more tricky and this shot is not zoomed in at all (a vehicle in the shot would have helped). The bottom of the coulee (Balka) is probably two to three levels below the 'hill I am standing on (its actually level 0 terrain, or the same general elevation of the surrounding prairie).
If I drop down to the spot where the two streams meet mid-frame and look up, I see this:
I was standing by the telephone pole at the top for the first pic. The road might even be considered "elevated" from the perspective of anyone trying to climb the slope from the coulee bottom to the road. A person who is fit can run up to the road in about 20-30 seconds, a minute or so more to the top. Definite minimum move terrain.
Looking right from the coulee bottom you can better see the effect of the slope from the hill to the road to the coulee bottom.
Standing on the road, level 1 hill with sunken road embankment to the left as the road slopes down into the coulee. This could be classed an an elevated road as a culvert carries the stream eastward under the road below.
