When I was 13，I climbed my first mountain-a fairly gentle 3，900-foot peak.I was overweight at the lime and out of breath when I reached the summit.But I loved challenging myself.Soon I'd climbed nearly 100 peaks.My parents were happy I'd finally found a hobby.
   I often go climbing with my friend Mel Olsen.She and I drove to tackle 11，240-foot Mount Hood.It's safer to start winter climbs at night when there's less risk of the sun melting the snowpack.That day，we started at3 a.m.Al around 9 a.m.，we reached an ice step.It was about three or four feet tall and sloped at a 75-degree angle.I volunteered to go first.I placed my left foot on the ice step.
   I gained a sense of the ice when I stuck my ax and crampons （鞋底釘） into it，and it felt good.Confident I was safe，I put my full weight on it.Suddenly，I heard a crack，and as the snowpack became thinner，a whole piece of ice broke off the step，right under my foot.
   In an instant，I fell backward，bouncing off the rock face and rolling down the mountain as if I were a character in a video game.I remember thinking，"This is it.You're done."I stuck out my arms and legs，grabbing at anything.That stopped my rolling down the mountain，but I was still sliding.After a few seconds，I came to a stop on a shallow slope.
   I asked myself：Where are you？Mount Hood.What's the date？December 30.Good.My brain was functioning.Then I checked my body to see where I was hurt.For the most part，I was fine，except that I was suffering from a sharp pain in my left leg.Later I'd learn that I'd broken my femur （大腿骨） and that the bone was slicing into my skin and muscle.
   At the bottom of Mount Hood，I was loaded into an ambulance and taken to a hospital.The doctors told me it would be a year before I could climb again，but I was back on the trails within six months.
