Elemag Reef (Rif Elemag \'rif 'e-le-mag\) is the 100 m long in southeast-northwest direction and 40 m wide moraine reef in Moon Bay, Livingston Island in the South Shetland Islands, with a narrow shoal extending for over 400 m eastwards. Surface area 0.33 ha. Situated 5.4 km south-southwest of Edinburgh Hill, 5.95 km west of Half Moon Island, 5.18 km northwest of Rila Point, 3.3 km northeast of Zlatograd Rock and 1.85 km east-southeast of Sindel Point. Formed at the terminus of merging Struma and Huron Glaciers, it was originally named Elemag Point. The current reef configuration is due to glacier retreat of up to 1.8 km in the area in the late 20th and early 21st century. Bulgarian mapping in 2009. Bulgarian topographic survey Tangra 2004/05 and mapping in 2009.
