HistoryA character grade: shown, never part of Dos Palos’ overall grade.
Few California towns list much on the Register (a typical California town has 0.0 per 10,000 residents, the U.S. 2.4), so Dos Palos’ 0.0 sits below most of its state (31% of California towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.

What stands out about Dos Palos’ past
Read from the archive, the National Register and the record. The page puts what stands out first.
In one of his expeditions during the 1820s along the west side of the San Joaquin Valley, explorer Gabriel Moraga reported the location of two large isolated poplar trees, which he called "Dos Palos". In 19th-century Spanish usage, palos was used to describe tall pole-like trees or "timbers". 21st-century usage often translates it as "sticks". The "Rancho Sanjon de Santa Rita" Mexican land grant cites "Los Dos Palos" or "The Two Trees" as a boundary marker.
