To Guadalupe Lake.

Gaspar de Portolá
The 1st of September, we proceeded for four hours and a half, the whole time over a mountainous road with very many sand dunes. We halted at a very large pool of water, near which there were two villages of about one hundred natives.

From the Ranchería del Baile de las Indias we directed our course inland, towards the north, leaving the coast in order to avoid the shifting sands of the dunes by which it is bordered, and other difficult places. It was not possible, however, to avoid a mountain chain that crossed our way, and extended from the interior of the country; but the sandy ground did not last long. We then proceeded over high hills, and through canyons containing very good soil and good pasture. We pitched our camp in a large valley, near a lake of great extent containing fresh water, it must have been some two thousand yards long, and as much as five hundred wide, possibly more in some places. We gave to the whole valley the name the Laguna Larga. It is three leagues from the place we set out from in the morning. There were in this valley two Indian villages: the one small and miserable, the other larger, being composed of several small houses.

At six in the morning we left the camping place, taking the road straight to the north, in order to avoid the sand dunes on the beach; but, although we went some distance inland, we did not entirely escape them, for we found some quite high ones a good way from the beach. After traveling about half a league we came to a sink, or pool, of fresh water, with an abundance of pasture which grows among the tules with which the pool is surrounded. The sand dunes continued for about three-quarters of a league, and then followed a ridge of firm land, covered with rosemary and little trees unknown to us. After a league and a half of travel we descended to a valley of good land well grown with pasturage, and continued over hills. After four hours travel, in which we must have gone three and a half leagues, we descended to a beautiful valley, about three leagues wide and more than seven long. In the middle of it there is a very large lake, more than five hundred varas wide and of unknown length, for we could not see the end, and it is surmised that it reaches to the sea. All along its banks there is a great deal of tule, many cottonwoods, and pasture without end. We pitched camp near the water. There are two villages, one small and the other larger, and as soon as we arrived the people came to visit us and made us gifts of some baskets of pinole and the seeds that they use. The water of this lagoon comes from a spring, and if it could be taken out much land could be planted. It is a very delightful place, and the view takes in the whole of the large valley. We gave it the name of Laguna Grande de San Daniel. I took the latitude and it was thirty-five degrees and thirteen minutes.
