Small bridge encounter for the player characters to root around and maybe find some goodies?

Notes:
The large tree to the bottom left has a man hanging from the tree. Maybe its a message? Maybe its a unfortunate adventurer or hunter/gatherer?

To the bottom right you can see a outline of a snow pile beneath the rotting fir that leads to a small cave that has a exit into the river below in case the bridge breaks? Or maybe its a hidden stash? Who knows.

The bridge has been reinforced with some chain and some planks to get across. Maybe it breaks?
