White Cloud campground, 4300 ft, 11 mi. E Nevada City (by rd), Nevada Co., Calif.
24 June I arrived last night and it was raining lightly then. It rained some during the night, then hailed. The hail continued off and on, mixed with sleet, until midafternoon. By 1800 the cloud cover was reduced to about 16%, mostly on the westerern horizon. No squirrels were seen or heard. I set traps out between 1000 and 1100 and was in the study area from 1000 to 1200, 1400 to 1600, when I closed the traps and went into Nevada City so I could get dry ice early in the morning. The ground was covered with single Douglas Fir catkins. There were many Ponderosa Pine catkins on the ground, too, and many still on the trees. The Sugar Pine catkins are almost ready and the balls of yellow can be seen all over the trees. The tips of some of the catkin-bearing twigs, about 3 cm. long, have been cut off and lie under the trees. Some have been completely eaten; most tips have only a couple catkins missing. Wind was high at times - 5-20 mph. Temp. was 38° at 1400, 40° at 1800.
25 June Though I tried to get dry ice early in the morning, the dairy didn't open until 0800. I got the ice then went to the campground. Then I spent 0830 to 1300, 1500 to 2030 in the study area, hearing 9 churring calls. I opened the traps as soon as I got to the study area and recaptured 2 squirrels. I marked them with a dry ice brand since their previous marks had only been with Lady Clairal. I found 5 immature Douglas Fir cones 5½-6cm. long on the ground. Two had had scales removed from the base/1cm. Sky clear, wind light. Temp. 48°F at 1000, 60°F at 1500, 48° at 2015.
