M. Brock 1957 Journal July 1 Barrow, Northern Alaska pressure ridge. This was the first sign of any ice breaking. Previous to June 30 the ice was frozen for about the first two miles from shore and with the pressure ridge located at this limit. Beyond this point ice was perhaps a mile more of ice. So yesterday the ice beyond the pressure ridge began to break. Today, July 1, was a sunny day. At 6700 today there was not the slightest remains of ice on the ocean. On the very distant horizon a few ice bergs could be seen. Apparently nearly everyone had missed the breakups which someone stated occurred about 1300 or 1700. July 2 made morning and evening checks of traplines V and VI made a utilization check of Transect IX. Drove to both and looking for traplines. Apparently the army has moved in on the area and most of the location is highly restricted with signs every where telling warning people of the fact.
