This site is presented to explore the role of public land in Panamerica through the legacy of the Mexican Ranchos of California. As you explore, imagine broadly what remedies can be offered to repair the land and the people who were recently disposessed and evicted from your region.
During the two decades following Mexican Independence the northernmost reach of the Mexican State, named Alta California, was sparcely populated compared to any time before the Spanish conquest or after American colonization, which would come as a deluge starting in 1849.
In 1845, by events leading up to the annexation of Texas, it was likely clear to the governor of Alta California, Pío Pico, that the American armies would soon seize the northern lands of Mexico. During this year he quickly granted the prime California pasture lands in vast swaths of public land to petitioners, well represented by friends, family members, allies, and himself. The boundaries of these land divisions often loosely defined in coarse sketches of mountains and creeks .
Mexican Land Grants, recognized by the Treaty of Guadalupe Hidalgo, within twenty years of annexation would be mostly be bought by speculators from Europe and Connecticut, and the many arms of the Atchison, Topeka, and Santa Fe Railroad Company.
Just as the earlier Mission system of Spain pushed indigenous people to the rocky boundaries of the Southern California landscape, the American colonization would by 1870 create defacto domination across previously sparely-populated land. By the year 1900 dammed rivers and citrus grove subdivisions would trace the grid of a Southern California that a comtemporary reader would faintly recognize. After the dam building binge of the 1930s the natural spaces dried up and so did most life making a living on the outskirts of the water department.
As I have, you will find these names are still inscribed in many small places on roads broken and unbroken that connect modern tracted-Southern California. And as we trace roads and creeks we will start to discover the layered landscape that has always been right here under our feet.
We begin our exploration starting with the southern most region of California, San Diego County.

River is the watershed the dam drains to, with the stream it sits on in parentheses. Completion year and storage capacity are from the National Inventory of Dams; storage is the current maximum, so San Vicente reflects its 2014 raise. Old Mission Dam dates from 1813–1816. Lindo Lake in Lakeside is a natural lake with no dam. Click a column heading to sort, or a dam name to show it on the map.

698 mines and quarries in San Diego County: working and closed mines from the state's Mines Online, with the year of their latest report, and historic producing mines from the USGS Mineral Resources Data System. Production years appear where USGS recorded them; "documented" is the year of the earliest report USGS cites for the mine, often the 1963 county mineral survey, not the year it opened.
