The canyon is oriented east-west, with the entrance from Klamath Downtown to the east. A crashed Enclavevertibird is on the western side, with the corpses of the crew next to it. The sole survivor of the crash, a crippled Mister Handy is located between the entrance and the crash site operating in defensive mode. A yellow reactor keycard can be found on the body of one of the pilots.
Depending on your actions in the brahmin related quests, Torr Buckner may be found hiding here.
The Vertibird was piloted by Daisy Whitman, and crashed due to rotor malfunction. Upon examining the vertibird, it is clear that the pilots are dead. This is incorrect - while the rest of the crew were not as lucky, Daisy herself was able to walk away.
