On the eastern bank to their left they saw long formless slopes stretching up and away towards the sky; brown and withered they looked, as if fire had passed over them, leaving no living blade of green: an unfriendly waste without even a broken tree or a bold stone to relieve the emptiness. They had come to the Brown Lands that lay, vast and desolate, between Southern Mirkwood and the hills of the Emyn Muil. What pestilence or war or evil deed of the Enemy had so blasted all that region even Aragorn could not tell.
- The Fellowship of the Ring (Book 2), Chapter 9
The Brown Lands are a stretch of ruined land south of Mirkwood and north of the Emyn Muil. They were devastated by Sauron in the late Second Age in an attempt to halt the advance of the Last Alliance toward Mordor. He also destroyed the Entwives who once had their gardens here.
