From the Western Snow Conference website:
The Western Snow Conference provides a forum for individuals and organizations to share scientific, management, and socio-economic information on snow and runoff from any viewpoint and strives to advance snow and hydrologic sciences.
The Conference is divided into four geographic areas: North Pacific, South Pacific, North Continental, and South Continental. Administration and leadership of the Conference is carried out by a General Chair and an Executive Committee with representation from each of the four areas.
