Photo by @shonephoto (Robbie Shone) // A geologist carefully enters a small chamber containing stunning cloud-like cave formations known as mammillaries. These formed underwater at times when the lake was much higher than it is today. The formations that look like lion tails (i.e., white stalactites with orange bulbs on the end) formed close to the water surface, with the white part being above water and the orange part being just below the water surface. This contrast between the orange and white formations can give you an idea of where the level of the lake was in the past. Lechuguilla is part of the Carlsbad Caverns National Park in New Mexico. It 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. @natgeocreative
