Hnífsdalur is a small village in the municipality Ísafjarðarbær, located between Bolungarvík and Ísafjörður. The name is literally translated as Knife's Valley. No mention is made of it in the Book of Settlement. Some guess the thin or sharp line of the mountain range resembles that of a knife. The single deadliest avalanche in Iceland of the 20th century happened there in 1910, killing 20.
