摘要

Between 2012 and 2015 National Cave and Karst Research Institute (NCKRI) personnel conducted electrical resistivity and microgravity surveys over Big Manhole Cave, located on public land administered by the US Bureau of Land Management (BLM) in the Guadalupe Mountains of southeastern New Mexico. Big Manhole is a relatively shallow pit cave, but it is thought by many cavers to be a second entrance to Lechuguilla Cave, the deepest cave in the continental United States. Digging in Big Manhole Cave has been occurring sporadically for many years, following airflow through cemented breakdown. Microgravity survey results show a negative gravity anomaly southwest of the cave entrance, consistent with results of a 3D resistivity survey conducted in the area by NCKRI staff in 2012-2013. Combined geophysical results indicate that a substantial void is present in the subsurface a few tens of meters below and extending to the south of the dig. The entrance to Big Manhole Cave is located <300 m north of the Carlsbad Caverns National Park boundary. Lechuguilla Cave is located within the Park, but at its closest point Lechuguilla is only 300 m from BLM administered land. If a connection is established between Manhole and Lechuguilla Caves, it will raise interesting questions about dual management of this unique natural resource.
