The Andover Township Cemetery is a large, well-kept cemetery on the south side of Andover that appears to be for both Lutherans (on the east) and Methodists (on the right). It was established in the 1860s.
There are many unique tombstones there, one of which appears to be a handmade concrete cross with rocks set into it at N 41° 17.242 W 090° 17.778. I moved the cache, so you will not see this stone on the way to the cache, but it's still worth checking out.
This cache should be easy to find.
