      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,a few days before my birthday. 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 corner. On the third day I was

struggling through stormy weather and during the nest week the wind grew stronger and I found myself

spending a whole day in my tent.

      I had traveled 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 the tent away, but none of that happened.
