For anyone interested in this topic, the Consolation magazine of May 27, 1942 that was mentioned above is well worth a read. Rutherford wanted to be buried at Beth Sarim and when that was not allowed by the local authorities, Beth Shan. There are of course many places here where he could have been buried.
Who actually knows where he ended up? Several sources suggest beneath the garage at Beth Sarim or somewhere on Beth Shan, it ran to several acres. The cellar under the goat barn was not found until many years later and is currently an underground 'den' beneath a property built in the 1950's. Plenty of links and photos to that on this site.
