The Junkyard is a location which appeared briefly in Season 4 of Fear the Walking Dead.
Nothing is known about the junkyard before the apocalypse. It can be assumed it was used as a junkyard for the residents of the state of Virginia.
At some point after the outbreak, a group of survivors made their home here and occupied it for some time.
After the war Morgan mentions to Althea and John Dorie, Morgan moves into the junkyard after its previous occupants moved out. He stayed here for an unknown length of time. During his stay, Paul, Carol and Rick visit him (separately) at this location trying to convince him to stay. Morgan leaves after an undisclosed length of time en-route to Texas.
