CSAS Hosts Snow Characterization Workshop in Silverton.

Thanks to the initiative of Dr. Hans-Peter Marshall and Dr. Martin Schneebeli of the  WSL Institute for Snow and Avalanche Research SLF,  the CSAS was able to host their fantastically successful, 3-day hands-on workshop in high-tech snow characterization methods and theory here in Silverton on March 18-20, 2008.  Marshall and Schneebeli discussed and demonstrated methods for snow casting and X-ray tomography,  snow micro-penetrometer measurement and signal analysis, near-infra-red photography and specific surface area characterization methods, and FMCW radar snowcover measurements and signal interpretation; Dr. Chris Hiemstra of Colorado State University also demonsrated the use of the MagnaProbe tool, another snow penetrometer tool used in extensive snowcover surveys throughout the Arctic and other shallow snowpacks.  All workshop participants agreed that this was a superlative experience and, for our part, we were honored to facilitate and participate.
