What happened

In 2007, on the eve of the Heathen Challenge ski mountaineering race, it snowed a foot.

Why it matters

The next day, 14 competitors lined up at Sunlight Mountain Resort in Glenwood Springs for the 11-mile race.

Common ground

When the leaders got to the top of the Heathen ski run they found the head of ski patrol there with a lit charge getting ready to blast the steep terrain.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
