Growing up in southern NJ during the 50s, cinder blocks were very common to
see lying around.  But I can't say to what extent and what purposes they
were used in actual construction since they were no where near as strong as
cement blocks.  Regardless, I doubt those cinder block in NJ came from AZ or
were made with volcanic cinder.

Mark,

My grandparents and dad bought "cinder block" in the late 1950s here in San
Diego and it did not have volcanic cinder in it. I suspect your blocks did
and you always assumed all "cinder blocks" had cinder.
