Excerpt from the report:

The Colorado Avalanche Information Center has completed its third year under the management of the Colorado Geological Survey and its seventh year within the Department of Natural Resources. The purpose of the Center is to minimize the economic and human impact of snow avalanches on recreation, tourism, commerce, industry and the citizens of Colorado. It achieves this through a dual mission of forecasting and public education.

Three forecasters shared the responsibilities of a seven-day work week during the winter season from November through April. That staff of four did an amazing amount of work, as is documented in the report.

Summary of avalanche events: A total of 1,391 avalanches were reported to the Center this season (25% below normal). Avalanche Warnings were posted on 20 days (15 below normal). Four people died by avalanche (normal). There was negligible property damage.
