The Midgewater Marshes were where Aragorn and the Hobbits Frodo Baggins, Meriadoc Brandybuck, Peregrin Took, and Sam Gamgee had to cross on their journey to Rivendell. Chetwood was on the western side of the marshes, and the Weather Hills were to the east. The terrain of the marshes was boggy and unyielding, dotted with pools and reeds. The marshes were home to biting midges and annoying cricket-like insects that Sam Gamgee dubbed "Neekerbreekers."
