Gaspar de Portolá Diary
We proceeded for five hours; a good road. We halted in a gully where there was sufficient pasture and water.

Miguel Costansó Diary

In the morning we broke camp at the place mentioned, and arrived at the spot previously reconnoitered by the scouts; it was given the name of La Poza de Osuna, and also of San Jacome de la Marca, the former by the soldiers, the latter by the missionary fathers. This place is a very picturesque and attractive canyon. In parts it is probably more than two thousand yards wide; it is entirely covered with pasture, with some groves of trees, and has much water collected in pools. Towards the west, and beside one of these, we pitched our camp at one o'clock in the afternoon. On our way we came upon two Indian villages, one about midway, the other in the very canyon where we encamped. All the country through which we passed was rich in pasture and not at all rough. We headed constantly to the northwest and north-northwest as the lay of the land permitted; the country was composed of hills of moderate height sloping into various canyons, all of which ran down to the sea, and the waters found their way into them by various creeks in which a quantity of salt accumulates. The Indians of the canyon immediately came to see us; they approached little by little, full of suspicion, and as they were greeted and presented with some strings of glass beads they quieted down and became so familiar with us that they occasioned annoyance. The scouts were sent out during the afternoon, and returned on the following morning with news that they had found a watering-place at a suitable distance.

Fray Juan Crespi Diary

About half past eight in the morning we left the place, following the same direction to the northwest. We ascended a large grassy hill, all of pure earth, and then found ourselves on some very broad mesas of good soft ground, all covered with grass, not having encountered a stone since leaving San Diego nor any other trees than those spoken of in the preceding valley, except that here and there we saw some very small oaks and chaparral. We saw seven antelopes running together on this mesa and at every moment hares and rabbits came running out. After about a league and a half of travel we came to a very beautiful valley, which, when we saw it, seemed to us to be nothing less than a cultivated cornfield or farm, on account of its mass of verdure. On a small eminence in this valley we saw a village of heathen, with six little straw houses. Upon seeing us, all of them came out into the road, in great good humor and making demonstrations of joy. We descended to this valley and saw that its verdure consisted of very leafy wild calabashes, and many Castilian roses. These heathen have near their village a pool of water in an arroyo.

This valley runs from southeast to northwest, and is about one league long and some four hundred varas wide, all of good pasture, with some live oaks and alders. We called it the valley of Santa Isabel, Queen of Portugal. We stopped a little while so that the commander might distribute some beads among the heathen of this village, and then continued on our way to the north side of the valley, with a heathen of the village who voluntarily offered to accompany us to the camping place. In about half a league's travel, at the end of the valley we came to a medium-sized pool of fresh water, in which we saw two pots of baked clay, very well made. Here we turned into a valley which lies to the north and traveled through it, over level land well covered with grass, from which we saw another valley better than the preceding, and went down to it. We pitched camp near a large pool of good, fresh water, which the soldiers called the Well of Ozuna, and which we called the valley of San Jacome de la Marca,(1) asking that saint to intercede with the Most High for the conversion of its heathen natives, and that a mission might be formed here, with him as its patron, since the site is apparently very suitable and invites it. The march this day covered three and one-half leagues.

The valley must measure about one league from north to south and about half a league from east to west; all the land is level, very verdant, with much pasture, many wild grapes, and other herbs. To the south of this valley there are three large pools, and to the north, according to the story of the explorers, there is a very verdant arroyo, and some other very large pools. Near the southern pools, on a slope, there is a large village of heathen and many well built houses with grass roofs. As soon as we arrived about eighteen heathen came to visit us, with their women and children, all very affable and not at all noisy. It seems that this place is near the sea, judging by our view of it as we came down the valley. The hills that surround this valley are not very high, and are all of pure earth, covered with pasture, the only thing lacking to the site being trees. Many scorpions have been seen, but no one has been bitten by them.
