tions to supply bases located miles from Little America for the planes on their exploration flights. These trips through blizzards and over dangerous crevasses provided the men with many thrilling adventures. On one occasion Peterson and a group had to dig a tractor out which became lodged in a 35-foot crevasse. They had to build a snow bridge under it and then dig a ramp in the hard-packed snow. The accident nearly cost the expedition one of the six motion picture cameras.
The cameras were taken along on many trips. Peterson made 21 flights with the camera. Herrmann made five. The longest dog team trip by surface was 1,220 miles. One plane flight was approximately that long.
