Hollowed-out rock (Fallout 4)

The hollowed-out rock can be found behind the Museum of Witchcraft and contains loot and a note.

Layout
The hollowed-out rock is behind the graves at the Museum of Witchcraft. It does not readily stand out as a container up close or at a distance, moving the Sole Survivor's view directly over the rock is required to notice it. The rock is shorter than the gravestones, nearly set into the ground.

 * Bottlecap x50

 * Note to S from E
