Ford of Brithiach
The Ford of Brithiach was an important ford of the River Sirion. The crossing was in the upper part of the river's course, on the northern borders of Brethil. A road led across it from West Beleriand into Dimbar, and then on into the perilous valley of Nan Dungortheb. The ford is often referred to simply as 'The Brithiach', a name that comes from the Elvish for 'gravel crossing' (Sindarin brith "gravel" + iach "ford").
