P. DeBenedictis 1965 Lemmus trimucronatus 15 June Bearow, Alaska - estimate density at about 20-30/acre on the ridge along Elron hogon. Animals quite noisy. Caught 7 animals from one position and jumped 5 from an area of 10 ft square. 16 June On the beach ridge in this area when Mullin & I collected them on June 12 the beasts were a little more conspicuous than last Tuesday; we got 11 animals from an area about 100 x 40 feet and got 3 without moving the weasel (Mullin is "clonulig"), and without beginning to hurt the population; missed 4 to 5. All were singles and saws at least twice as many others. They are digging mainly in the tundra along the edge of the quells & seem less inclined to flight than on the 12th. Density was higher, 77 June Dondon #1 of ridges seen along clearings on the south part of the Beach Ridge & Elron hogon. Some grubbing seen here, and they are fairly noisy under the ice. 17 June In the area between S. Salt hogon & Family hogon saw only 2 Lemmings, sawt about 25 in an equal sized area (120 acres) to the south of this; 18 June Almost no signs thus in the Barrel areas (but they are common on the Beach Ridge, the few animals we have taken being unnoticeable got 30/3s and handle 2 about 10/4s from an area about 1 acre and didn't to tell pop.
