Lozen Saddle

Lozen Saddle (Lozenska Sedlovina \'lo-zen-ska se-dlo-vi-'na\) is a 437 m high saddle situated between Lozen Nunatak and Zograf Peak in Tangra Mountains, eastern Livingston Island in the South Shetland Islands, Antarctica which provides overland access from the Wörner Gap area to the Shipka Valley. The saddle was first crossed by the Bulgarian Lyubomir Ivanov from Camp Academia on 17 December 2004, and takes its name from the adjacent Lozen Nunatak.
