The Tangra 2004/05 team covered either on ski or on foot an overall distance of some 200 km, mostly in harsh weather conditions and challenging unfamiliar terrain in eastern
Livingston Island , including the first crossing ofBowles Ridge , and first visit and routes toVidin Heights ,Gleaner Heights ,Melnik Ridge ,Levski Ridge ,Saedinenie Snowfield ,Kaliakra Glacier ,Struma Glacier , middleHuron Glacier ,Leslie Gap ,Elhovo Gap ,Gurev Gap ,Yankov Gap ,Pirdop Gate ,Lozen Saddle , and the peaks Lyaskovets, Zograf,Lozen Nunatak ,Erma Knoll ,Aheloy Nunatak , Ravda, Komini, Ongal, Melnik,Castra Martis Hill , Radnevo,Zemen Knoll , andMiziya , as well as the third ascent ofPresian Ridge and the summit Mount Friesland.Extensive geodetic and geographic information was gathered, including coordinates and elevation data, actual sea shoreline and ice-free zones configuration, as well as a detailed photographic documentation of previously unexplored and remote areas in the interior of
Livingston Island andGreenwich Island .Results
Based on the survey, 146 geographical features were mapped for the first time, and the coordinates of other 8 features were updated. A new 1:100000 scale
topographic map of the islands of Livingston and Greenwich was published in August2005 in 1802 hard copies, and also made available in electronic version both in the website of the Ministry of Foreign Affairs ofBulgaria , and in theWikimedia Commons .In connection with the work carried out by the Tangra 2004/05 Expedition, 126 new Bulgarian names for hitherto nameless geographical features on Livingston Island and Greenwich Island were approved on 11 April and on 4 November
