I had previously posted on Camp Hayden and what I believed to be its first patch.  Either that patch is from a later year (which seems more likely), or there were multiple patches issued.

Camp Hayden was last run by GNYC in 1974.  My 30+ year old memory was that it was closed in 1975 and reopened in 1976

During this time period (mid-1970’s to the early 1980’s) Camp Hayden was leased to Rockland County Council.  Pictured below is a dated patch from 1976.
