Wait out the storm...

You decide to hunker down for the night in the makeshift shelter; and you're pretty sure that a lot of the wargs (large ferocious dog with spikes for fur), chameleons (medium sized carnivorous reptile that can blend into any environment) & bears are on the prowl for stragglers anyway.

You pat yourself down to check your meager supplies.

You have:

1 stone dagger

1 day(s) worth of foraged food

2 worn out shoes

1 worn out cotton tunic

1 dilapidated leather belt

1 small pouch of buttons (currency used by your tribe)

"Grr, me not have fire making thingies..." You chide yourself for losing your survival pack 2 days ago while tumbling down a ravine. You've been searching for a way out of the ravine since you fell and have found no success.

With no way of defending yourself in the event of some larger stronger creature seeking shelter from the rain in the same fallen tree you must decide to either make a trap or dig a tunnel deeper underground.
