Vaca Mountains – WorldAtlas

The Vaca Mountains are part of the interior ranges of the northern California coast. They are bordered to the north by the Putah Canyon, to the south by the Suisun and Sacramento valleys, to the east by the Vaca and Pleasants valleys, and to the west by the Gordon Valley and Wragg Canyon. The Vaca Mountains form the eastern edge of the Napa Valley, shielding it from the scorching heat of the Central Valley.

Geography of the Vaca Mountains

The Vaca Mountains.

The Vaca Mountains extend from latitude 38 0 16 ‘N, just north of the town of Fairfield, to latitude 38 0 31’ N, where Putah Canyon serves as a barrier that separates the range from the rest of the mountain. 325 mile long boulder that borders the west side of the Sacramento Valley. The Vaca mountain range is approximately 9 km wide and 28 km long, covering approximately 250 km². Blue Ridge is the backbone of the Vaca Mountains and stretches the entire length of the range and exceeds 600m elevation for most of its length and gradually lowers south near Fairfield, where it disappears at the head of the Suisun valley.

History of the Vaca Mountains

The Native Americans who inhabit the Vaca Mountains belonged to the Patwins, meaning “people” and used by several tribes of related cultural qualities to refer to themselves. One of the most famous Patwins was Chief Solano, a friend of General Mariano Guadalupe Vallejo, Mexican commander of Sonoma and surrounding areas. Solano County, one of the first counties in California, was named after Chief Solano, who was named after the baptism in honor of the 17th-century Franciscan missionary, Saint Francis Solano.

The Vaca Mountains were part of four Mexican land grants, Suisun, Tolenas, Los Potus, and Chimiles. The low altitudes of the Vaca mountains were used for agricultural purposes. The lands were favorable sites and were cleared for planting vines and orchards. The oaks of the Vaca Mountains were cut down for fuel in the 1850s. Tolenas Spring, in the southern part of the Vaca Mountains, was a former Indian spa. Its water was then bottled and remained popular until around 1905. Today, all the land in the Vaca Mountains is private, with the exception of a few square kilometers, which is used for the public near the northern slopes of the range.


Like most of the California coastal ranges, the climate of the Vaca Mountains is Mediterranean-type and has cool, wet winters and hot, dry summers. Vacaville is a town in the Sacrament Valley east of the Vaca Mountains. This is an altitude of 32 and the average precipitation is 634 mm, as measured by the nearby National Weather Service station.
