Summary

How old is the Grand Canyon? When did the glaciers last retreat from this area? How long does it take to form an inch of topsoil? When did the earthquake occur that formed these rock scarps? These are the questions that geomorphologists ponder. This chapter will outline the tools and approaches we use to answer such questions.

Establishing how old a landform might be, that is, when it formed, has always occupied the mindset of geomorphologists. If we know how OLD a landform is, then we can begin to understand how it is evolving, how fast it might be changing, and how it formed in the first place. Fortunately, various dating principles and techniques now exist to address these issues. These techniques require the ability to measure change in a system or a landform over time, with the (usual) goal of establishing the age of a sediment package or a landform.
