Our purpose is to explore and better
understand changes in the landscape of southern Minnesota over the
past 150 years. We are retracing Nicollet's expedition routes, juxtaposing
descriptive passages from Nicollet's diaries as well as those of his
partner, botanist Charles A. Geyer, with photographs of the modern
landscape, chemical testing of water quality in lakes along his routes,
and a reconstruction of changes in productivity and eutrophication
in these lakes and surrounding watersheds using dated lake sediments.
