A lot of us have seen the static map of Ypsilanti from 1868. The Library of Congress took that map and scanned it in high resolution and made it so it can be navigated. Here is the link to that map — Map of Ypsilanti 1868
If you look at the map you’ll notice that in the upper-right corner of the map is the Peck orchard which is now the Prospect Park Neighborhood. The only substantial building on the lot North of Forest Ave was Fred Swaine’s Malt House (Link to Historical Society story) The Swaine house now located on Forest and River was not built nor was the Hutchinson Mansion on the opposite corner of Forest and River.
