T. Cobe 1958 September - cont- along the sides of the troughs. Reminiscent of Wainwright Type 2 in spring '57. A few fresh pellets and 1 pile of cuttings noted in a runway. 25 traps set in troughs covering an area of 50 x 50'. (2) dwarf willow area 6" to 18" high, growing among small diameter (4-8") tussocks on well-drained gravel 1/4 mile back of the willage. This area of about 200 yds x 20 yds is literally riddled with old holes and runway trails in all directions around the tussocks. The larger willow bushes serve as loci for burrowing just as was the case at Wainwright in 1957. This group is on a low ridge and is not obviously patterned. 30 traps set in an area of 20 x 80 feet. No fresh sign observed at any point. (3) on right limit of river ca 1/4 mile from the willage along the upper zone of virginian willows in an area of flat centered polygons (edge-grown willows) covered with tussocks) with narrow & shallow troughs - ca 4-6" wide at top x 3-6" deep - usually just wide enough at bottom to make suitable passage for
