Produce a detailed written description of a gloomy wilderness setting with trees, grass, and a swamp.

A slight, widespread depression in the forest floor has gathered waters from previous floods. The ridge along the riverbank blocks the drainage of water back into the river. Clumps of long-bladed grass have popped up randomly in dry areas of the swamp. Once mighty trees now lie rotten and moss-covered, victims of the soft ground's weakened support.
