I don't like avalanches, either. Related Wonders for You to Explore Match its definition: spoiled or ruined or demolished. I was skiing alone first mistake and not even wearing a beacon second mistake. After all, I wasn't skiing, I was working, tightening the bolts at the base of each chairlift tower with a torque wrench.

Even in my ignorance, I could see that it was hardly a subtle situation. Over a foot of new snow had fallen the night before and it was blowing hard, loading up the steep slopes beneath the upper section of the chairlift with thick slabs of wind-drifted snow. When I was finished with the tower at the top of the avalanche paths, I started to walk up the slope so I could gain the ridge and circle around to the tower on the other side of the avalanche paths.

But since I didn't bring my backcountry skis or climbing skins third mistake , what was an easy ski down was an exhausting pig wallow back up and the cliffs were too scary to climb in my slippery plastic boots.

So I couldn't help but notice that there was only a foot wide couloir that separated me from the safe slopes on the other side. And naturally enough, I thought that a good skier like myself should be able to get my speed up and zip across it before anything too bad happened fourth mistake. I did my ski cut according to the book. I build my speed up and I crossed the slope at about a degree angle, so that in theory, my momentum would carry me off the moving slab in case it did break on me.

Since I had never been caught in an avalanche before, I had no idea how quickly the slab can pick up speed after it shatters like a pane of glass.

I heard a deep, muffled thunk as it fractured. Then it was like someone pulled the rug out from under me and I instantly flopped down onto the snow losing all the speed I had built up. So like a startled cow, I sat there on my butt and watched soft slab instantly shatter into little blocks and the blanket of snow rocketed down the slope as if sucked downward by extra heavy gravity. I jumped to my feet and tried to build up my speed again so I could jet off to the side.

But the blocks were moving all around me, like tumbling cardboard boxes blowing in the wind, and nothing seemed to work. It was only two or three seconds after it broke and the avalanche, with its unintended passenger, was already moving a good 20 miles per hour.

Looking downhill, I saw a line of small trees coming toward me at a frightening speed, looking like a line of periscopes slicing through the water toward me, like an old war movie. I tried to maneuver to grab one of them. But the avalanche, as I discovered, pretty much has its way with you, and choice is one of those things you think you might have before you're caught in an avalanche, but never afterward.

Luckily it took me directly into the smallest tree and I slammed it hard and grabbed on with all my strength. The snow pounded me, like standing under a huge waterfall and it felt like my neck would snap as each block of wind slab smashed into my head.

Luckily, grabbing that tree probably saved my life because it let most of the debris pass by me debris that is below you can't bury you but unfortunately, the tree eventually snapped off, and I quickly rocketed down the slope again.

Then the tumbling started, over and over like being stuck in a giant washing machine filled with snow. My hat and mittens were quickly ripped off along with both my skis.
