The adventurers found 2 additional things near the ravine.

The first was a series of glyphs written in Dwarven alphabet, but not in Dwarven language.

Spoiler: If you know Goblin language
Show


The signs mark the terrain as goblins' territory and are a warning for everybody who would like to go deep below.



The second thing was an old fire, maybe a month old. Some people had their stop here, and tried to hide its track after they went further, Gods only know where.
