On March 29, Crespi and Fages continued along the shore, reaching the western end of Carquinez Strait, "traveling by treeless, grass-covered hills." They continued along the steep bluffs on the south side, probably nearly to Martinez. "In the whole distance we traveled on these hills there was not a single tree. The bed of the estuary is very deep and its shores precipitous; on its banks we did not see so much as a bush ..." The last statement is interesting in view of the evidence contained in the accounts of Font and Anza (see p. 133). Several native villages were seen. "On the banks of the other side we made out many villages, whose Indians called to us ... and many of them, seeing that we were going away, came to this side, crossing over on rafts, and gave us some of their wild food." On the south side: "In this part of our day's march we came to five large villages of very wild heathen ..." It is probable that the expression "this part of the day's march" refers to the first portion, i.e., from Pinole through Rodeo and Crockett. There the natives had "... pleasant faces, and were of a fair complexion, bearded and white, all with long hair which they tied with twine." On March 30 the expedition set out and in two leagues crossed Pacheco Creek (see Bolton, 1927, p. 295n), which was a "deep arroyo with much running water" and bordered with trees. This reference to "running water" raises the question of local water supply, a matter that will be discussed more fully in connection with the Font-Anza descriptions. The plain between Walnut Creek and Concord is described as being well covered with grass and grown with oak trees. In this valley two Indian villages were encountered. After crossing the low hills northwest of Concord, Crespi and Fages entered the delta region of the Central Valley and camped somewhere near Pittsburg or Antioch. The next day, March 31, it was decided to return. Accordingly, the steps of the preceding day were retraced as far as the area of Walnut Creek, whence they turned south to the night's camp near Danville. (This itinerary has been worked out by Bolton and is no doubt substantially correct.) On April 1 the party reached Pleasanton via San Ramon and Dublin, and on April 2 arrived near Milpitas. The valley at and south of Walnut Creek is described as being covered with grass with the stream beds overgrown with alders, cottonwood, laurels, roses, and other shrubs. The same type of land, "covered with grass and trees," continued as far as Pleasanton. Then: "It is evident that the land is not so good now, but it all continues full of oaks and live oaks...." Crossing the hills to the shore of the Bay the same rough, wooded country persisted--essentially as it is today.
