Landscapes develop and evolve through an interacting series of processes – climatic, geological, ecological and cultural – over varying periods of time. These processes shape the structure and character of the landscapes which we experience. Over time, distinctive patterns emerge – ranging in scale from the distribution of small plants to the sculptured sides of a huge canyon. Our perception of these patterns goes beyond just their visual appreciation – beautiful though they may be – into a richer understanding of how we experience our environment.
