Ko ford Cynomys ludovicianus July 30, 1955 Wind Cave Nat' Pk., S. Dak. afterd to N. since 1951 (see Cole map). W. of road in Basin Flats. Sloping dog present 1951. Slope of most bottom about 2%, good slope direction like main part Malach Dam Town. Dogs mainly at S. side of bottom of upslope this side, to 250 yds. W. of road. Much Baja this general area where slope steeper. About 50% grad, base where C.L. Bajr. downster. Beyond area dogs, seem about 2' tall (and steller) but not teeth. In area occasional patches of Baj- Baja, & there after the area with C.L. burrowed (favor first? or made by C.L.? ). Some burrows dusting wallower made other openings wag., but no C.L. burrows in these. Lower population along this area - about 1/4 man ft. slope when most; some up to 15% slope (S. side valley). Much Baja cut near used burrow. Saw Burr Ridge from ups, & some cut at dam near burrow (eat local swelling?). Sedge indicates wet spots here? Many mss. centers in area Bajr-Baja dominance - 10 yds. Drain, often, was Arist. find, & Baja around. Took same photo this. A burrow 200 yds. W. of road freshly bedgends (cassium, dry, present). Spot no bur- row within 100 yds. Highway (S. side valley) where slightly high ground, Baja < 10%, mostly Bajr-Baja. Out on flat ground, some low mounds 30' across, 3-4' high, mostly with Bajr-Baja seen). In area surrounded by tall Baja. Many of these large mds. with C.L. md. on top. Perhaps large mds. old C.L. mds., fawn grey. Definitely C.L. an area short rather than wild-groce dominance here. Flat ground may sometime be too wet for C.L. Last even- ing I saw had Buffalos here. At Mule Creek Tkt, E. central Wyo. Revisited around Town line. Killed evidently poor at least 15 day seen in area about 5A on slope. Now seen in bottom
