In the fall of 1674, Marquette remained in the Chicago region because he was too ill to travel to Kaskaskia, where he intended to serve as a missionary. So he spent the winter in the Chicago area along the south branch of the Chicago River. His account of his months in Chicago show the importance of the river and Lake Michigan on the landscape, as well as the kindness of area Indians for this lonely man.
