In page Cuyamaca Rancho State Park:

"

The park is located on the 1845 Rancho Cuyamaca Mexican land grant. With the discovery of gold in Julian in 1869, the Spanish, Mexican, and American governments and settlers changed the Kumeyaay's way of life forever. Disease spread through the Kumeyaay, traditional ways of life were destroyed, and promises broken as the Indians were expelled in 1875 from ancestral lands and taxed without representation. Currently there are about 20,000 Kumeyaay descendants in San Diego County, 10% of whom live on the 18 reservations which range from 6.3 to 122,000 acres (0.025 to 490 km2).
