- How it worksHow do antecedent, subsequent, superimposed, relict, geometric, and consequent boundaries each get made?

- Going furtherWhat happens to a relict boundary that no longer divides anything politically?
- Common mistakeWhy isn't a boundary that follows a mountain range automatically an antecedent one?
