I'm using a 1970/71 plat map of Keokuk County. Ioka is still shown on that map.
Start at the junction of highways 149 and 78. Drive East on 78 for 3.5 miles.
At this point go north for 0.5 miles, east 0.25 miles and north 0.5 miles. The cemtery should then be on the right, east side of the road.
Ioka: Start at junction of 149 and 78. Drive east on 78 for 4.25 miles. Ioka starts at this point on both side of highway 78 and extends east for another 0.25 miles on the north side of the road, 0.5 miles on the south side of the road.
