If Glóin is right, Bilbo Baggins may have ventured north into the Misty Mountains instead of returning to Rivendell.
If Bilbo did come this way, some of his tracks may have survived being covered by the recent snows.
More of Bilbo's tracks may lie to the north, hopefully not covered by the recent snows.
A small camp-fire to the north-east of the tracks may conceal some sign of Bilbo.
Perhaps Bilbo evaded the goblins at the camp-fire and journeyed further north. You should search for more tracks in the wide-open space at the top of the slope.
A goblin-camp to the north-east lies directly in the path of the last tracks you found. What was Bilbo thinking?
A dying goblin lies among the slain. Did he see Bilbo?
