Koford 320 Cynomys ludovicianus November 29, 1955 Nr. Ft. Collins, Colo. into the northern "home", no contraction out of southern "hom." Later had 3 C.L. near are burrows, but in general dogs were seen singly. Good cover of early Bda about 1" tall, 4 cattle still grazing on part to 5. of fence. Much more grass cover than December 1954. Few mule deer (1/2% or less). Bases of Bda grew still. No signs of cutting all Bda in spots, & no obvious digging for roots. 1/10 curren, clear, light breeze, 4 near freezing, but comfortable in sunshine. Doubtful that any shot here this year, though from canons might get a fair shot at me at about 120 yds. range. Very wary in gail. Aram half green some after but no evidence current eating any C.L. Probably feeding on Bda mainly. 11 1/2 mile N of the E-W fence are old burrows that, last spring, I investigated & decided were unused. Today I saw 2 C.L. there, possibly intruders from another area. Vegetation sparse & shot there. 11 Dog droppings on many roads of the Spring Canyon Dam colony. 11 The work of old dog class deer showed are 22.4 burrows/A. on area E edge 2 1/2 acres (5 X 5 chains) just 5 of fence with E edge at lowest bottom. 8 measurements of max. slope of highest burrow at E. edge and 9 to 15 3/4 Topo. (x 1/2 for 9%), median 12 3/4-13. Near apparently active over 13 1/2 T. Penetrater measurements near 20 burrows gave readings 140 to 280. Harder (to 300) on ridge to E. above upper limit burrows. December 6, 1955. In afternoon visited Spring Canyon
