Christmas 1959 Journal 134 26. 23 Contra Costa-Alameda Co., Calif. We proceeded down Skyline Blvd. to Redwood Rd where we turned down the canyon & on down, continued past San Leandro Reservoir. Photos from opposite the dam. On W, facing hills directly south of the dam we noticed Baccharis invading the grassy areas. The hills here are very interesting for the east facing slope is mainly Baccharis, minor amounts of evergreen oaks and some isolated clumps of Acer macrophyllum and Emblactus c - as far as I could determine from flaccities. Further down the canyon - above L. Chabar is an extensive area of riparian growth - mainly Salix, Alnus, Umbellularia (which was blooming everywhere where we observed it). Visited the Narrows on Crow Canyon Rd. Left that & proceeded up the road & turned down Norris Canyon Rd. The country here is open grassy hills with dense riparian growth and limited groves of oaks. Photos just over ridge looking east. San Ramon - Danville, etc. to Pleasant Hill and dark then Alhambra V - (Bear Hampton Rd. Impressions: There are two main "communities" - Baccharis and Broad-leaved leafy forest. They mix in places to the extent that the oak is interspersed with the shrubs. The rather different riparian growth should be considered a broad type typical over much of the state. Sycamores were rare - (saw on Crow Camp Rd.) The grassy areas is a paradox - a count (figure is not as yet. Many extensive & recent) landslips - most from last year I believe. Where does the Baccharis meet the Charnie to the S?
