Alone in Antarctica
At 50 I was the first woman to travel alone to the North Pole. But what should I do to celebrate my 60th birthday? What else, but a journey at the opposite end of the world, Antarctica. I began my almost 400-mile journey on November 1st, 1997. I walked and skied alone. My dog team were not with me to pull my sled. Another journey of challenge and danger was about to begin.
The first days the weather was very good. The wind was icy but not very strong and there was bright sunshine 24 hours a day. But changes were just around the comer. On the third day I was struggling through stormy weather and during the next week the wind grew stronger and I found myself spending a whole day in my tent.
I had travelled only two hours one day when the winds increased so much that I had to put my tent up before the winds became too strong. Within a few minutes the winds increased to a howling storm that threatened to blow me and my tent away, but none of that happened.
On November 12th the storm died down. It was my birthday and I wanted to make that day special. I thawed a frozen cake over my fire, placed a candle on the top, lit it and sang "happy birthday" to me, at the top of my voice.
A few days later, I was moving forward over a slope that seemed safe when suddenly without warning my worht dropped out from under my skis. I had fallen into a hole and was hanging on the ropes tied to the sled. A piece of ice fell down and I never heard it land. The bottom was a few hundred feet below. I used to practice self rescue many times in the mountains where I live and carefully began climbing out. It took a long time but I finally got out. I was thankful for all the training I had had.
I was in good health and all of my equipment was working well. I was so optimistic that I decided that the next day, the 22nd day of. the expedition, I would increase my workday to 12 hours.
The next morning I had a bad accident with the sled and hurt my leg. I couldn't stand on my left leg and my head was woozy from hitting the ground. But I knew that I had to get up. Lying on the ice, I would soon die. I struggled to my knees knowing that somehow i had to put my tent up for shelter. On hands and knees I got the tent up and dragged my sleeping bag into the tent and lay down out of the cold wind.
I had to make a decision. Wait to get better or give up? I had to think of my family, which is very important to me, and do the right thing. I did so without regret. I had met the challenges of solo travel in an extreme climate. It is an experience I shall never forget and shall value for the rest of my life.
