During the second week of February four people of our group (Katee Wendt, Gabriella Koltai, Yuri Dublyansky and Christoph Spötl) spent several long days in Devils Hole 2, continuing our FWF-funded research on the unique calcite deposits of this cave. Supported by staff members of the Death Valley National Park (Kevin Wilson, Jeffrey Goldstein) and three highly motivated students from the University of Minnesota we managed to obtain a series of up to 90 cm long drill cores above the water table, as well as 40 cm-deep cores down to -1.5 m. We also made a survey linking Devils Hole 2 and Devils Hole proper which revealed that the groundwater table differs by less than 6 cm between the two sites, which are 200 m apart.
