If you read the accident summary, it explains that neither of the snowboarders were carrying any safety equipment. This is so tragic, this death was easily preventable. CAIC (Colorado Avalanche Information Center) deemed the avalanche danger as level 4 / high for this area of the state and if these people knew what they were doing, this wouldn't have happened. Up to two feet+ of snow and extremely high winds made backcountry travel heinously dangerous at the time.
So NS, please, please don't go skiing in the backcountry if you don't know what you're doing and don't have proper equipment. Be safe and enjoy your winter.
Here's the accident report.
