This is a replacement for GC6NJ4F which replaced GC57TDA. It's a popular stop along the Lincoln Highway, even now that US Highway 30 has been re-routed about a mile to the north. The last two caches at this location are gone, but the reason for your visit remains...THE Lincoln Highway Bridge. Learn more at: https://en.wikipedia.org/wiki/Lincoln_Highway_Bridge_(Tama,_Iowa).
This edition of the LHB cache is a camo bison container. It should not be too difficult to find in any season, so don't go out of your way to look for it. There is no reason to venture west behind the monument, or to approach either the bridge or creek (unless you want to get a closer look at the structure of course).
