I also wanted to mention that the person that put these listings on find a grave, took them from the Idaho County GenWeb site.(without permission)
The Lot/Block online at Genweb are the old format for this cemetery and are from the original plat books. The cemetery was originally laid out in random rows and made it hard to identify one row from another.
Thanks to the Idaho County Genealogical Society and the Cemetery district, they are in the process of adding new row markers to make it easier to find a grave.
