Walnut Creek in Contra Costa County, California — The American West (Pacific Coastal)
Mt Diablo State Park
What's In A Name?
On a 1824 map, "M. del Diablo" signifies a Christian Indian village, not a peak. The reference to "diablo" or devil can be traced back to 1804 or 1805, when a Spanish military expedition visited the area in search of runaway missions Indians.
At a willow thicket several miles northeast of here, (near present-day Buchanan Field) the soldiers encountered a village of Chupcan people and surrounded it. But that night, evidently all the Indians escaped. Angry and confused, the Spanish called the site "Monte del Diablo" or Thicket of the Devil." Later English-speaking newcomers mistakenly applied the title to this prominent East Bay peak. A linguistic accident thus gave California its Devil Mountain.
General Mariano Vallejo's account was somewhat different. In an 1850 version, Vallejo placed the incident at the foot of Mt. Diablo, claiming that the Spanish were routed when an "unknown personage" or "evil spirit" appeared. In 1914 Vallejo's son, Platon, made his father the hero who lassoed this "agent of his master, the devil."
With its unobstructed view, Mt. Diablo's summit has long been an important reference point for land surveys in the far west.
On August 2, 1921 - with Senator W. Starkey as the main supporter - a bill was signed into law creating a state park on top of Mt. Diablo. In 1931, Mt. Diablo was re-dedicated as a unit of the newly born State Division of Beaches and Parks.
Between 1933 and 1942 Civilian Conservation Corps workers transformed the young park constructing roads and trails, ranger residences, and many of the camp and picnic facilities used by visitors today. This stone summit building is literally the CCC's crowning achievement on Mt. Diablo.

Also see . . . Mount Diablo -- Wikipedia. It is an isolated upthrust peak of 3,849 feet (1,173 m), visible from most of the San Francisco Bay Area. Mount Diablo appears from many angles to be a double pyramid and has many subsidiary peaks, the largest and closest of which is the other half of the double pyramid, North Peak, nearly as high in elevation at 3,557 feet (1,084 m) and about a mile northeast of the main summit.
