Mayhew 1958 Oct. 10 Barton Flats area, San Bernardino Co., Calif. rocks, basking in the sun. We located a rather good collecting spot for our transect work at about 4100 feet, which was 5 miles on up the Mill Creek Road toward Barton Flats. The 5000 foot collecting site, 3'1/2 miles further up the road, and 2'1/2 miles below Camp Angelus, doesn't look very easy to work. However, it should provide sufficient animals for our study. This spot is in rather precipitous country, compared to the 3000 & 4000 foot sites (both of which are in the stream bed). The 6000 foot site is 2'1/2 miles above Camp Angelus, and 3 miles below the Jenks Lake turnoff. This area looks to be easy to work. We ate lunch at Barton Flats campground #2 (6260 feet elevation, about 1 mile above Jenks Lake turnoff). The South Fork campground, about 3 miles on up the road from Barton Flats campground #2, but at the same elevation, was our next stop. We collected several Uta stansburiana and Sceloporus occidentalis here. No Sceloporus gracilis were seen, although we have several in our collection from here. The air temp. Journal 106.
