To Buena Vista Creek, northeast of Carlsbad.

Gaspar de Portolá
The 17th, we proceeded for three hours on a good road; we came upon a village without inhabitants. We halted in a gully where there was sufficient water and pasture.

In the afternoon we left the place just mentioned, the country having already been examined by the scouts. We travelled for three leagues. The country was of the same character as that just covered; that is, composed of low hills of black earth, readily traversable and easy of approach, and covered with pasture. We came to the watering-place situated in a moderately wide canyon. The water issued from two different springs and stood in pools, about which it formed some miry places or marshes, covered with reeds and pasture. We pitched our camp upon a slope on the western side of the canyon, and gave the place the name of Santa Sinforosa. From our camp one could see, on the top of a low hill, an Indian village. [The inhabitants,] warned of our coming by their neighbors of San Alejo, sent two of their number to beg leave to come and visit us. We gave them to understand by signs that they should defer the visit until the following day; but forthwith they went back to their village, and in a short time all the inhabitants came [to our camp] — there must have been as many as forty men, well-built and good-looking. The leader or chief soon afterwards began his harangue with loud cries and odd grimaces, but, without giving him time to finish, we made presents to him and his people of some glass beads and sent them away.
In the morning they returned and remained quietly amongst us until our departure.

At three in the afternoon we left the camp, following the valley in a northerly direction. In a little while we climbed a very grassy hill without rocks, in open country, then traveled over mesas that are in part covered with grass and in part by a grove of young oaks, rosemary, and other shrubs not known to us. Aside from this all the land is well covered with grass and is mellow. After traveling about a league we descended to a valley full of alders, in which we saw a village, but without people. In passing we named this valley San Simon Lipnica.(1) It is not very far from the shore, and at the end of it we saw an estuary, although the sea was not visible. We continued on our way in the same northerly direction, over hills and broad mesas supplied with good pasture, and after about one more league's travel we descended to a small, very green valley, which has a narrow plain some fifty varas wide. We pitched camp on the slope of the valley on the west side. The water is collected in pools, and we noticed that it flowed out of several springs, forming about it marshes, or stagnant pools, covered with rushes and grass. We named this place Santa Sinforosa.(2) We saw from the camp a village of heathen on the summit of a hill, who, having been informed by their neighbors of San Alejo, deputed two of their number to ask permission to visit us. They were given to understand by signs that they must put it off until the following day, as it was late, but, as soon as they went back to their village all its inhabitants came to camp. Not fewer than forty presented themselves. As soon as they arrived their leader made his speech, with excellent gestures; but without waiting for him to finish his harangue, he and his people were given some beads and dismissed. The next morning they returned and remained until our departure.
