Munro's remains were recovered from Guadalcanal in 1947 and were reinterred at Laurel Hill Memorial Park in Cle Elum in 1948, his family having declined a full military burial at the Arlington National Cemetery. In 1954, the City of Cle Elum expanded Munro's gravesite with the installation of two decommissioned Mk22 naval deck guns to either side of the tombstone. Munro's parents were later buried on either side of their son's grave at Laurel Hill. The entire site has since been added to the Washington Heritage Register as the Douglas Munro Burial Site.
