Journal 26 June Tahoe National Forest, Nevada Co., Calif. I wanted to find a good study site for Tamiasciurus applying these criteria: (1) accessible during the winter, (2) relatively flat and free from undergrowth and dead branches (3) good chickaree population. I started looking around Hwy 20 at about 1200. I went down the Lowell Hill Ridge road, 2 1/2 miles west of Emigrant Gap on Hwy 20. Heavily logged and lots of undergrowth, in addition to being hilly. I then checked the first couple miles of the road to Gold Bug mine, 1 mile north of the previous turnoff. This area had some flat parts, but there was a lot of dry dead branch debris on the ground. I then checked in the region of Harmony Ridge, about 5 miles east of Nevada City, going down to the nature study area. The forest there was mature, but on a steep slope. I finally checked the upper area of Steephollow creek, 3 1/2 miles west of Lake Spaulding. It looked good except for the logged areas and a lot of debris on the ground. I did see one squirrel there, though. I spent the night there. There had been no cloud cover all day, wind was light. Temperature was about 50°F in the morning, rising to ~70°f by noon
