Koford, R. 1975 Journal White Cloud campground, 4300 ft., 11 mi. E Nevada City (by rd.), Nevada Co, Calif. 6 July I spent 0610-1245, 1515-2045 in the study area, hearing 5 churring calls, catching 2 squirrels, and finding a nest hole. By early afternoon many of the people were gone from the campground. The sky was clear, wind 0-5 mph, temp. 60° F at 0800, 76° F at 1530. 7 July I spent 0615-0730, 0900-1315, 1530-2030 in the study area, catching 2 squirrels and hearing 7 churring calls. In the morning I went into Nevada City for dry ice. There were several camping spots occupied and people gathering wood in the study area. Sky clear, wind 0-5 mph. Temp. 59° F at 0730, 78° F at 1400, 64° F at 2030. On the way into Nevada City this morning, I looked at a crushed juvenile on the road near the 24.65 mile marker - it was a mole.

Then I went into Nevada City for supplies, planning to get dry ice in the morning. I found a dead one on the road at about the 23.00 mile marker. She had nipples about 4 mm long, 3 mm dia., with areas of thin fur around them, but I couldn't find any placental scars. The uterus was about 3 mm. across at the base of the horns. I saved the skull, even though it was smashed, to look at the teeth. I also saved the eyes to get less wt. data. Sky clear, wind 0-5 mph, temp. 62° F at 0800, 80° F at 1500, about 70° F at 1830. 9 July 7 mi. E Nevada City (by rd.), 4000 ft., Nevada Co, Calif.
