Location: It is located on the bank of Sapši Stream which is one of the two major branches of Kizilcik Stream which empties into Sakarya River; 2 km west of Kizilcik Cave in Karasu District of Sakarya Province. It is on a lightly declining plateau type surface which was splitted and crumbled by the rivers.
Structural Properties and formation : It has similar geological characteristics to those of Kizilcik Cave. It was developed horizontally in NE-SW direction. It is a sinkhole/spring type semi-active/active fossill cave. The total length of the cave is 314 m. It has three entrances; it extends making right angle turns or curves depending on the fragmentation system and layer direction of the limestones. The spring type main entrance looking over the Kizilcik Stream has an altitude of 106 m; and its height from the stream basin is 40-50 m. The second entrance is located 60 m southwest of the stream entrance. The third entrance is 15.5 m above the first entrance located at the end of the cave. Bataklidere bears many forms and structures that characterizes a multi period development. But due to the minimal width of the limestones and that there is a layer of impermeable rocks underneath them; keep the cave from enlarging deeper (lateral enlargement); therefore the height of those forms are not much. The cave ceiling was collapsed or about to collapse due to the same reason. In addition the dripstone formations are very few. Bataklidere Cave is filled with a thick layer of debris; sand; pebbles and heaps of rubbles. The subsurface stream flowing over this sediment forms shallow ponds here and there.
Research History: It was researched by Geological Studies Department of MTA General Directorate; and published in 2002.
