Greetings to all:
Philip has a very good point if the base of the monument is the original base from 1914. Build the base, place the time capsule and lower the large headstone.
jbuck also has a valid point but use an industrial X-Ray on the monument to see what is inside the monument base. It would be simple enough to set up and less costly than chipping away rock. The X-Ray would need to look at the base with cross directions.
Marquette might have an industrial X-Ray service that could help.
