The heroes are being chased through the wilderness when all of a sudden they come across a gaping hole or canyon. There's no bridge or obvious way down; the heroes are trapped! Except then one eagle-eyed adventurer (usually the youngest or least experienced) notices a conveniently located log or fallen tree that can be used as a makeshift bridge. It may already be lying across the gap or it may have to be moved into position. Sometimes it takes the form of a tree growing on the edge of the abyss that can be chopped or knocked over. Almost always has the bridge breaking or somebody almost falling off during the crossing. Once the heroes have crossed, they usually push the log into the hole to keep their pursuers from following.
