Nimthond

The Nimthond (S. "Whiteroot") was a tributary of the River Lefnui in Anfalas. Although narrow and unnavigable, the Nimthond was swift-flowing all year round and could not be forded within thirty miles of its confluence with the Lefnui. Nimthond was an important watercourse, both because it marked the first great bend in the Lefnui and because it cutted a sure path to the Cirith Nimrais where it originated.The level character of the land surrounding this pass resulted in marshes and bogs where the headwaters of the Nimthond converged, creating a significant, though by no means perilous, obstacle to crossing the pass.
