The National Cave and Karst Research Institute (NCKRI) is a nexus of research, stewardship, outreach and information for caves and karst while fostering interdisciplinary collaborations, created by the US Congress in 1998 in partnership with the National Park Service, State of New Mexico, and the City of Carlsbad.
NCKRI is located in Carlsbad, NM, and is a research center of the New Mexico Institute of Mining and Technology.
The ghost town of Berlin, Nevada, was established in 1897 as part of the Union Mining District after the opening of the Berlin Mine. At its peak, the town had about 75 buildings and 300 residents. It never prospered to the same extent as other boom towns like Tonopah and Goldfield, and declined following the Panic of 1907. The site was largely abandoned by 1911.
The site was acquired by the state of Nevada as part of Berlin-Ichthyosaur State Park in 1970.
