Walnut Hill Cemetery is located at 1350 East Pierce Street in Council Bluffs, Iowa. Walnut Hill is really five cemeteries, with a long wall crypt garden across the street, all clumped together at the northeast end of the city. Along with Walnut Hill, there are Cedar Lawn, Ridgewood, St. Joseph Catholic, and Oak Hill/Bikhor Cholim. The entrances all radiate off of the same street, so they are fairly easy to find.
The first map below is my interpretation of the cemetery boundaries with names; if anyone knows differently, please email me. The second map is without the boundaries.
