Prepare to get your hands dirty with a whole new perspective at Agua Mansa Pioneer Cemetery Field School!


Agua Mansa Pioneer Cemetery, or “gentle water,” is one of the last remaining pieces of a paradise long past. The terrain once offered a variety of resources and strategic vantages for the people living here.

To the Serrano, the Cahuilla, and the Gabrielino/Tongva, the Santa Ana River offered both resources and a connection to tribes along its banks, creating river communities that were multiethnic and multilingual.

Agua Mansa and La Placita were among the largest settlements between New Mexico and Los Angeles during the 1840s, and they were just across from each other along the banks of the Santa Ana River. These communities were the first non-native settlements in the San Bernardino Valley, and featured the region’s first church and school.

Today, the Agua Mansa Pioneer Cemetery is one of the few remnants that still exist of these once-thriving communities; its last burial occurred in 1963.
