July 17 Point Barrow, Alaska and energy was consumed just in living. There was one inconvenience of working on the ice pack. That was because there was a periodic shifting of it. Sometimes this resulted in crushing of the work shelter, and some- times in casting it temporarily adrift from the ice island. Once the shelter broke in two. These ice movements were always gradual enough to that most of the equipment could be salvaged. Five times during the winter it was necessary to change location of investigative operations. Ocean depth there was 7000 feet. This base has opened a new field for Arctic Research, allowing long time observations in this area that have not before been possible. It will be remembered that there is no land mass at the north pole as is so at the south. The ice islands are termed "T" because they appear as "targets" on the radar device of weather aircraft that cruise over the region. Having a base within the region of the pole allows for less flights of weather aircraft, for much data can be accumulated and realised out at intervals. The camp, or base, was about a mile from the edge of the island. Some of the details that apply here are available
