R.J. Ratt 1957 2 Journal Dec. 26 Sawmill Mtn, 5200+ ft., 7mi. W, 2mi. N Lake Hughes, Los Angeles Co., Calif. The older maps do not show this dirt road, but the newer (dates?) editions of the Automobile Club of So. Calif. map of Los Angeles and Vicinity show it very well. We arrived at the summit at about 10 AM and collected in the vicinity until about 4 PM. The main ridge of the mountain is fairly level for a length of about 1½-2 miles, but it is narrow with a level area only about 30-50 yards wide on top sloping off very steeply to the south but more gradually to the north. The vegetation on this summit area is dominated by yellow pines. They are not very thick but are rather sparse and occur in small clumps. For the most part they are large and tall. There are numerous dead ones both standing and fallen. The other main tree in the summit area is a deciduous oak (Q. ) which is quite abundant. They are without leaves and have shed a good crop of acorns. On the south edge of the summit the pines break off sharply, and a dense chaparral occupies the steep slope. To the north the forest extends down slope for about ¼-½ miles. On the north slope of the mountain the sheltered draws contain stands of Bigcone Spruce at elevations as low as about 4000ft and this tree occurs on three sides of the Yellow Pine stand—north, east and west. It also occurs in the summit area in two draws that extend down from the top toward the north. The northern, lower edge of the yellow pines is a mixture of the yellow pines, Bigcone Spruce and a few Bigger Pines. The understory of the pine-Pseudotsuga forest is largely grass.
