Yes.


...errr, you just tricked me into a one line answer.
A violation of the ATS rules.

I guess I should elaborate.



It's like topography, or elevation lines showing the altitude of a mountain.
But sence the stream is more like a river, it tends to be in a line.
In the case of these isolated loops it's similar, by analogy,
to a loop of the Mississippi that is cut off and
becomes a lake.
