Sherburne Friend Cook, The Aboriginal Population of Alameda and Contra Costa Counties…
“ On the northeastern shore this bay is surrounded by high ranges of hills. At the mouth there is a luxuriant forest of live oak and another even larger at the upper end, together with a heavy growth of redwood. On the southwestern shore is a small estuary navigable only by small boats, and on the same shore two inlets in which anchorage is possible. Another, to the east, has a rancheria of Indians like those at Monterey. This coast appears to have locations very suitable for missions, although I examined them only from a distance. ”
