The datalogging and time-lapse experiments by RL were funded in part by the NASA Applied Information Systems Research (AISR) program, and other visits to the playa were supported in part by the Cassini Radar (RADAR) program. BJK acknowledges a research grant from the Geological Society of America and discretionary support from the director of the Lunar and Planetary Laboratory of The University of Arizona. We thank David Choi and Catherine Neish for assistance in the field. We are grateful for the assistance of David Ek, wilderness resources coordinator at Death Valley National Park, in conducting the in situ measurements. The authors gratefully acknowledge Cynthia Cheung and the NASA Lunar and Planetary Sciences Academy for support of the publication of this work. We thank three anonymous reviewers for their careful reading of the paper and for suggestions that led to its improvement.
