E. sandy plains occupy an area of 965 square miles, and here also lies the large lagoon of Guanacache. The principal rivers are the San Juan, the Jachal, and the Bermejo.

The mineral springs, chiefly sulphurous, are used in the baths at Laja, at Pismanta, and at Florida, near San Juan. The dry climate is against the cultivation of the soil, excepting near the rivers, where artificial irrigation is used, and where maize, wheat, lucerne, fruits, and grapes are grown.

What Has Changed in the Last Century
Two of Collier's six San Juans have been transformed. The Argentine city of "about 15,000" was flattened by the earthquake of 15 January 1944, which killed roughly 10,000 people across the province; relief work for the disaster helped launch the national career of Juan Per on on a new grid, and the province now holds some 780,000 people and ranks second in Argentina for wine. The island Collier's still called Porto Rico was officially respelled Puerto Rico by the United States Congress in 1932, and its city of San Juan is now a metropolis of several hundred thousand; the Tewa pueblo northwest of Santa F formally readopted its own name, Ohkay Owingeh, in 2005. The lagoon of Guanacache, described here as "large," has largely dried out as the San Juan and Mendoza rivers were dammed and diverted for irrigation.
