Maclean 1966 much smaller than the ones I saw (1 Aug) earlier by the pitfall traps. So is a surface food source later than most. After lunch Tom went out to pull in two traplines. Niko and I went to our Chironomia pans - did well. Caught Tom going back in and spent the rest of the afternoon and evening sorting and counting. 20 August Barrow, Alaska Another day devoted to 'picking worms' - we've got over 12,000 small ones now. There is no doubt that the small and large chironomios are stratigraphically distinct, and clearly separate semi-pale from pectoralis and red-backs at this time. The latter two species are less easily (or less clearly) (or not!) separable. In the evening a very dense fog came in, and Wien was unable to land. 21 August Barrow, Alaska Up early, and Niko and I went to church again with Sara's family. Niko spotted Janet Gerhart fresh off the morning Wien flight,
