As stated on the ISSW website:

We cordially invite you to join other snow scientists and avalanche practitioners in attending this biennial International Conference celebrating “A Merging of Theory and Practice”. Set amidst a rich history of alpine skiing and snow sports in the spectacular Lake Tahoe basin this meeting of the minds provides our unique industry with a forum in which to discuss theories, present papers and explore innovative new research topics during a five day period of interaction and conviviality.
