I'm saddened to hear such bad news. I just read the article. I do wear a helmet, but I don't think it would've helped her. The article states she died of internal injuries. It was on Mount Ellen, which is Sugarbush North.
We had another death last week. A male snowboarder age 29, hit a tree at speed, and died of the injuries. He was supposedly a solid rider, and wearing a helmet. Last week was firm and fast. Every year a few people die on the hill.
