Tarlang's Neck the long, mountainous spur of the southern White Mountains, between the sources of the Blackroot and Ciril rivers. It thrust out between the Blackroot Vale to the west and the land of Lamedon to the east, joining the main range to three peaks.
Tarlang was the original name of this ridge, but it was later taken as a personal name.
A local legend among the indigenous people of Gondor told of giants and one of them called Stiff-neck who tripped and broke his neck. The other giants did not clean up his body, which became incorporated in the land instead. The giant's neck became Tarlang's Neck, his head Dol Tarlang, and the stones he was carrying Cûl Veleg and Cûl Bîn.
