The Vault 63 Crashsite is an unmarked POI added in the Skyline Valley Expansion for Fallout 76 and is featured in the quest titled "An Unlikely Invitation”. The location is located not far from Wayword & the local town of Sutton.

A friendly wastelander known as Alyssa is found at this location and can be spoken too during "An Unlikely Invitation” and after completion of the quest too.
