In the case of the Marine Corps, HRS-2 Bureau Number 129049 crashed on a remote California mountaintop southwest of Las Vegas on November 20, 1952. The site reports are below and since it appears the main rotor blades had been carefully removed that at least a partial salvage was begun/anticipated before the entire wreckage was clearly destroyed in place. The skins of these were an aluminum/magnesium alloy and burned quite readily.

It was surveyed the following spring and according to the testimony of the civilian who eventually salvaged the helicopter, was slated for demolition in place. In re-reading the article myself, Greenlee states the USMC was going to demolish the aircraft in accordance with Forestry Service Regulations. Whether or not an aircraft was destroyed may have depended upon the land upon which it crashed. Perhaps searching for old forestry department documentation will provide an answer.
