| Geography and Environment: The Kembos Plain; which is 1 km wide and 15 km long; drains the snowmelt during the spring time and waters gathered by the Uzunsu Creek; together with Büyük Düden (sinkhole) and Feyzullah Düdeni (sinkhole). The water being swallowed by these sinkholes flows into the Manavgat Brook; passing through the Altinbesik Düdensuyu Cave. The Büyük Düden sinkhole; which is 714 m long; has plenty of lakes; giant whirlpools and siphons. There is a 120 m descent until the first muddy siphon; which is 9 m long and 2.5 m deep. Then; it leads to a small hall; following a 60 m long passage. On the southeastern part of the hall; there is a lake and a second siphon; which is 31 m long and 10 m deep. The cave ends up with a 480 m long passage following the siphon [Jager et al. 1989:2]. |
