Lemmus trimucronatus 7 July -cont- the heavy winter cutting typical of the Barrow previous peltws out about 3 miles south of the gas well. From there on cuttings and nests to are quite local in individual marshes - mostly the intermediate ones in terms of wetness - the Carex aquatilis and Scirpus stands. At S. Bar-3 I examined 19 winter nests, one of which had some left of Lemming how in it. No other species were found. 23 July Colquille River - at Double Knife block Bluff - an adult Lemming was seen winding along the base of the bluff and into some low alder-willow brush. A number of fresh cascanes were found at raeagh-edged hawk nest (see under the account of Buteo lagopus for 22-25 July). September Arneat - Carex, the dog, caught a subadult on the up land brackish heath tundra just below T3. I took it away from their environment and put it in my coat pocket, but later it escaped as I was walking back to camp.
