Land forms were discussed thoroughly in the Introduction to Water Boundaries course.
A good example of land form evidence is from the Ferry Lake case on pages 175 – 177 of the 1973 Manual. (Page 264 of the 2009 Manual)
In referring to an original meander line, the Manual states,
“Along most of the meander line there was no indication of there ever having been a lake bank or water washed escarpment of any kind.”
