Understanding the long-term evolution of glacial landscapes requires a variety of different methods, such as an in-field stratigraphic reconstruction to a more technological based modelling approach. The use of remotely sensed data and spatial numerical models that predict landform development over time scales offer us a unique opportunity to witness the changing dynamics of a glacier throughout numerous glaciations. These spatial models offer researchers the opportunity to not only reconstruct past landscapes and how they have changed to the present, but also to extrapolate out into the future. This research will compare the accuracy of two glacier reconstruction models, Open Global Glacier Model (OGGM) and GlaRE, in an alpine glacial system; Sinks Canyon, Wyoming. These models both represent the self-developed tools used, now, to reconstruct past glacial environments. To reduce the error in glacier and climate interaction models this research will compare the outputs to illustrate which model is more appropriate for alpine glacial reconstructions.
