Book of Mormon External Evidences: Nauvoo Mounds

 The mounds in Nauvoo are at the end of Main Street going north.  I turns into Sycamore Haven Drive and follows the Mississippi.  There is a Y with Sycamore Creek Drive going to the right.  It is up this road, which turns to gravel that you reach the mound site.  The mounds are marked as an archeological site.  The tour guide said that an archeologist visited the area and felt that this was an ancient fort site.  

Looking across the Mississippi to Iowa to what may be Zarahemla

Across the river from Nauvoo is Montrose, Iowa.  In the D&C 125: 3 Let them build up a city unto my name upon the land opposite the city of Nauvoo, and let the name of Zarahemla be named upon it.

Some people take this to mean that the ancient city of Zarahemla is across from Nauvoo.  There is some speculation of a temple site being there just opposite the Nauvoo Temple.
