Tall Trees is a mythical location in Red Dead Redemption.
Tall Trees is a large woodland area found in the northern part of West Elizabeth, and it's home to big animals such as bears and elks. In the Undead Nightmare DLC, a Strangers mission can be played which involves John Marston hunting down Sasquatch beasts. After the missions is over, it's revealed that hunting the Sasquatches was not acceptable, and that the player has slaughtered the last remaining Sasquatch beasts. There the player is given a choice to either kill, or save the last Sasquatch alive. Although it is unknown what happened to the last Sasquatch, it is assumed, that he stayed in the woods for a century, before getting shot and skinned.
