Comments: The grotto is active in West Texas and S.E. New Mexico.
Ongoing projects include CRF Carlsbad Caverns, and the PBSS Rock Haul at
Carlsbad Caverns. The grotto also manages several caves in West Texas
including Ess Cave for friendly ranchers who have given them access for
recreational caving and exploration.
