Koford 1955 70 Cynomys ludovicianus March 9, 1955 NW Weld Co., Colo. Rod poisoned 1954. Saw 9 Antilocapra nearby, found coyote carcass & found apparent coyote droppings near it in 3 burrows. No fresh C. l. works seen. Most mounds on bottom of ¼ mile wide draw (not stranded) where slope 1 to 270. Some up east side bank to 1270 slope (face W). None atop thin bank when land was level 20' above level of bottom. //0 paced distances between 5 to 9 burrows in approx. straight line; 4 trails, one: 14 yds. on 1-270 slope, 16 yds. apart (also 16 yds. & 19 yds. 2 other trails), + 15 yds. on 570 slope. So fairly constant average below about 17 yds. All but 2-6 routes was 15½ yds. No mounds over 8" tall. Surface soil neither loose or fine sandy.; gravel in subsoil as shown by mounds. On much of flatter ground aristida conspicua. It makes up about 10% of plant cover at most & stands 6-8" high Baa & Bgr = (Buckler - Pantlana) while Bw - Bww only 1-2" midheight. // Returned to Dec. 22, '54 catch in traps; closed & left them. I saw 3 still out 4 p.m. in 30 mph warm wind; sky 8/10 ci.; 4 alto-cumulus. March 10, 1955 Nr. Ft. Collins, Colo. Visited Spring Canyon Dam colony 5 to 7 p.m. Found my saw chip camouflag had blown off of some traps and 3 C. l. in traps. There may have been less than 2 (07 31) or 3 (07 29, 07 30) days. 07 29 was in burrows, having pulled wooden drag to entrance. Upon being killed this we let out much apparent pomer. 07 30 had gone around around rock gap drag, forming a cone of earth, but no digging down. 07 31, at about 6:30 p.m., in dark, had burrowed under edge of mound come nearly out of sight from surface. All 3 had 2 ot fleas (cord). I took eye traps 3, 6, 7, & 18, + set new traps nos. 19, 20 & 21. 07 29 nos. in trap 3, 07 30 in T 3, 07 31 in T 43. March 11, 1955.
