These guys are up at 4 a.m. and out in the mountains November-April. They are one of the strongest avalanche centers in the country because of their knowledge, creativity and ability to communicate in a simple, clear way.
Because they forecast for such a broad area, the GNFAC relies heavily on backcountry user input and observations. The more standardized these tests become between all users, the better our communication and understanding can become.
