This detailed and colorful geological map is from Owen's report, submitted in 1851 and published in 1852. Assisted by J. G. Norwood, C. Whittlesey and other noted scientists, Owen's report made major contributions in several fields. The map itself shows an abundance of geological formations via hand coloring. It also shows the Iowa coal-field extending into northern Missouri and part of the Illinois coal-field. Inset at top shows the North Shore of Lake Superior. There is excellent detail of watershed and lakes throughout. A very graphic and well colored map.
