Grand Portage National Monument Preliminary Soil Survey National Park Service

This study was requested by the park in recognition of the need for soils information to assist in understanding the forest ecosystem, potential fire effects, management of trails and buildings, and for interpreting the Monument?s cultural landscape. Existing soils information for Cook County provided only a very broad overview, with little or no field investigation to verify soil types or provide information at a level of detail pertinent to or useful for park needs.
