This activity is designed as both an introduction to GIS and an exploration of topographic steady-state. Students analyze DEMs from Taiwan to extract topographic profiles across the range. They reconstruct a series of datasets presented in Stolar et al., (2007), showing the progression of the range to steady-state as a space-for-time substitution from south to north. Students are expected to relate their observations from the topography to theoretical concepts discussed in class including accretion and uplift, steady-state, and critical wedge theory. An extension involves developing a simple numerical model in Excel of a mountain range as it progresses to topographic steady-state landscape, allowing students to investigate the rise of a mountain range to steady-state both from Taiwan data and from their numerical model.
