These formed underwater at times when the lake was much higher than it is today. The formations that look like lion tails (the white stalactites with orange bulbs on the end) formed close to the water’s surface, with the white part being above the water and the orange part being just below the surface. Lechuguilla is a very beautiful and highly protected cave. Access is very strongly controlled and only given to experienced cavers with specific scientific or exploration goals within certain parts of the cave.」6月20日 3時20分
