Contour Lines

| View Cart ⇗ | Info

A contour about to cross a stream runs up one side and down the other, making a V where it crosses, the angle of the V pointing up stream. Contour lines representing spurs between stream lines are generally U shaped with the bottom or rounded part of the U pointing down hill.
