Vista Clara’s NMR geophysical instruments have played a key role in the comprehensive East River Experimental Watershed study conducted near Crested Butte, Colorado. GMR™ non-invasive NMR surface measurement, along with both Javelin® and Dart™ portable NMR borehole logging have all been used effectively in this multi-organizational study.  The study, which began in 2014, supports the collective research activities of multiple US Department of Energy funded investigators seeking to understand the drivers and controls of mountain hydrology.
