Restored LA-A 59B, El Morro, New Mexico Metal Route Arrow
Not all arrows were concrete. Metal arrows were easy to remove when a beacon site was shut down. This 9B El Morro, New Mexico emergency field arrow was salvaged and restored in Grants, New Mexico.

Relocation of airways left concrete arrows behind at many of the sites, but when the site was re-installed in 1930-31 (mostly) the arrows were non-critical due to  radio navigation signals, voice radios, enclosed cockpits, and better sectional charts. Only rarely across the US were arrows em-placed as of 1932. These were mainly the rare 1930’s metal arrows shown above but were not always on airfield sites.
