The purpose of this research was to analyze all of the avalanches in Colorado from 2001 to 2021.

All data was downloaded from the Colorado Avalanche Information Center. CAIC

Hypothesis: The areas of Southwest Colorado will have the greatest number of avalanches. Southwest Colorado averages the most snowfall, the mountains are steeper, and have higher altitudes than the other areas of Colorado.

After looking at location I wanted to compared the number of avalanches that happened at, above, and below tree level. The altitude of tree level in Colorado is roughly 12,000 feet.

Next, I wanted to analyze how avalanches were triggered over the past twenty years. The Colorado Avalanche Information Center broke the avalanches into two categories, natural and artificial. Within the artificial triggers there were four categories: vehicle, human, explosions and miscellaneous.

Finally, I wanted to compare the total number fatalities from avalanches in Colorado to the total number of fatalities from avalanches in the United States from 2001-2021.

Recommendations Based on Findings: Avalanches are a natural hazards but ofter are triggered by human activity. My hypothesis is supported that the Southwest portion of Colorado had the most avalanches based on their steep mountain faces and high altitudes but there were more north of Denver around Denver than expected. All that can be advised from this data is to get avalanche trained to gain more knowledge of how to avoid avalanches and what to do in the chance of getting caught in one. Stay updated on weather patterns and check the Colorado Avalanche Information Center before going out.
