The formation of the Mima-type mounds has been a puzzling and contentious topic. This study started as an idea for an undergraduate GIS lab. I was interested to see if I could use ArcGIS tools designed for hydrology analysis to classify the Mima mounds. High-resolution elevation data made this possible and I was able to identify over 27,000 mounds in five different prairies in southern Thurston County. A dataset of this size allowed subtle, but statistically significant, morphological and spatial characteristics to be identified.
