Log Drift|Coon Bridge in Go Down, Moses (Location)

"Coon bridge" in Go Down, Moses crosses the Tallahatchie River downstream from the site of Old Ben's death (231). It's not easy to see what the label refers to. At the same spot in the earlier story "Lion" is something called a "log drift." But whether "Coon bridge" is a tree that fell across the river, a literal 'logjam' in the river, or a rude structure over the river made of logs fixed together somehow, or something else - this can't be decided.
