Photo by @shonephoto (Robbie Shone) // A geologist enters a beautiful side chamber filled with fine rimstones, gours and other delicate cave formations. For millions of years, Lechuguilla has been sealed off from human and animal interaction.
The cave, which lies in Carlsbad Caverns NP, NM 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
