This is an extensive and informative report on the geological and mineralogical survey of the mineral lands in Michigan lying south of Lake Superior and north and northwest of Lake Michigan. The purpose of the survey was to determine which lands should be classified "mineral lands" and which "agricultural lands". Included in the congressional mandate was a provision for the establishment of a General Land Office in the northern part of Michigan to manage the sale of the state's mineral lands. Jackson spent two seasons on this project and then resigned. The work was completed by two of his assistants, J.D. Whitney and J.W. Foster. It contains four small plans and the following five hand colored geological maps:
1) Geological Map of Isle Royale Lake Superior, Michigan Foster and Whitney. (25 x 17.5").
