All international borders are "manmade", aren't they? "Straight" ones
are the exceptions. Most borders have components that are short
segments, but its rare that one of them take no turn whatsoever
"enroute" from one end to the other. The Delaware circle is truly a
peculiarity, because the usual border markers that shows either a
straight line or a line with an angular kink showing the border's
"incoming" and "outgoing" directions on it's top, could not be used on
this border in Delaware - the indicator would have to be an arch.
Would similar border markers around oases have a straight, angular or
circular indivator on top (i.e, is the border around any of them truly
circular to where an arch on a border marker would be the only true
indicator? Or are these borders around oases only made up of short
straight segments that look circular on maps?
