Then I realized it wasn't brown ink; it was dried blood.
The name Mark Finch was scrawled across the cave wall in blood. Under that was Jim Foster, under that Max Keller, and Samuel Ladd under that, all scrawled with differing writing styles. The last name was Lance Moore, which wasn't as weathered as the others as it had probably only been there about eight months if it was written right after his last journal entry. I guess this is where they all came to die, which meant there should be bones around here somewhere.
That was a lovely thought.
