Pre-contact The park is named for Brushy Peak (elevation ), a mountain in the
Diablo Range, that has had historical significance dating back to
Native Americans who lived in the region before the arrival of European settlers. It was a focus of trade routes that connected the Bay Area
Ohlones,
Bay Miwoks, and Northern Valley
Yokuts. According to the EBRPD, "The Ssaoam triblet of the Ohlone peoples was probably the most closely linked to the Brushy Peak area, living in the surrounding dry hills and tiny valleys around the peak and nearby
Altamont Pass. Ssaoam populations in the dry summer months may have dispersed and reconverged at various camps throughout the year." ==Notes==
