So begins day four of our canal travels.  We traveled from Starved Rock to a portion of the canal west of Ottawa.  We walked approximately one and a half miles.  During our travels, we found large supports for a bridge of unknown significance.  From here we reached Lock 12.  We walked back and then traveled to Buffalo Rock Stage Park.  We had a spectacular panoramic view of the Illinois River. From here we traveled farther east and again accessed the I and M canal. Here after a short walk we reached Lock 11. This is apparently a hybrid lock containing old and newer elements.
We then traveled to LaSalle, Il. where we visited Saint Vincent Cemetery. There is a commerative plaque to the many men who died working on the canal and died of infectious diseases. Their remains were transferred from a poorly kept Cemetary to this current location.
We attempted to view Locks 14 and 15. However, this area was inaccessible due to flooding of the Illinois River.
