A map is availvble at: http://herriman.maps.arcgis.com/apps/webappviewer/index.html?id=588744a8e1724f66b2c57e59a32a5605 There is also a kiosk at the back of the cemetery, but the information there is often outdated.
If your plots are occupied then they will be listed online with the names of those occupying the plots, through the Herriman City website. Otherwise call Herriman City and ask for who is over the cemetery and they should be able to tell you.
