The chart shows all profiles using a common base for elevation and horizontal distance.

The horizontal black lines placed at 15-meter intervals mark the contour lines on the original topographic map. The letters A to E indicate changes in slope from A (15 meters) to E (90 meters).

This chart suggests that there are terraces at A and D, but there remains the question are the terraces real or merely artifacts of the mapping process? Doubt arises because there seem to be breakpoints near each 15-meter contour line.
