Tree Shaped Tombstones - Way Over the Top in Janesville, Wisconsin

I had occasion recently to pass through Janesville Wisconsin.  It is the sort of older, mid sized community that is prime hunting for "Tree Shaped Tombstones".  I was not disappointed.  At the Oak Hill cemetery I ran across this gem of a family plot:

In addition to the large central "tree" there were little stumps marking each corner of the plot, and for good measure a pair on either side of the stone in front with the family name CULVER.    It seems the Culvers really liked this style.

But what the heck are those things on either side of the main monument?

They must have been custom carved from "segments" of a generic tombstone.  And what's with the tops?  At first glance you'd think these were seats, a place to sit and contemplate the Departed Culvers.  But are they?

Looks a bit uncomfortable even if that lump did not have initials carved on it.  Purpose unknown.

The craftsmanship on this set of "trees" is quite good.  Take a look at the base area:

Now take an even closer look!

Either a mouse or squirrel, and in either case a nice whimsical touch.  Well done Culvers!
