Public Comment Request 2005

Contra Costa Times 2005

What's in a Name?

In 2005, an Oakley man proposed changing Mt. Diablo’s name to a fictitious Indian word, Mt. Kawukum, because he believed the mountain’s name celebrates Satan.  In March 2005, the U.S. Board of Geographic Names began considering his request and and after public comments period denied the request at their board meeting. Now, still upset over the devilish connotations of Mount Diablo, the Oakley man has yet again petitioned a federal agency to rename Contra Costa's signature peak. This time he wants to rename the 3,849-foot-high mountain after the 40th president of the United States — Ronald Wilson Reagan.

The Contra Costa County Board of Supervisors Legislative Committee has recommended that the Board of Supervisors oppose the name change.  You can join them by sending a letter to:

How Mt. Diablo got its Name

“On a boggy day in 1806 {1805; 1806 is a discredited date} a detachment of Spanish soldiers apprehended a band of Bay Miwok Indians in a marsh at the foot of a solitary California mountain. Commanded to redeliver the natives to the stern grace of the mission they’d fled, the Spaniards detained them in a nearby thicket as night fell. A dun darkness came on, browning out the stars. The night grew quiet but for the din of crickets. Then at some deep and slippery hour the Miwoks vanished, turned to vapor and floated away in the mist, dematerialized as demons were known to do. The next morning the soldiers woke in a dawn steam thick enough to blank the big mountain from sight. They found themselves bereft of their errant mission-folk and turned round on their heels till their heads swam. Bedeviled as they were, they forswore the place Monte Del Diablo, Thicket of the Devil, and for years the name lingered like a fog over that marsh. Then when the English-speaking settlers arrived, the Spanish Monte was taken for Mountain and was thought to refer to the twin-shouldered mass looming nearby. So the mountain became Mount Diablo, made to bear an unholy namesake.”

Mount Diablo, (Wilkes) c. 1837-1841, misidentified post 1805

(San Juan Bautista, 1790; Cerro Alto de los Bolbones, Oct. 1811;  Monte del Diablo land grant, Aug. 24, 1828; peak and range Sierras Bolbones and Montes Diavolo, 1837; Monte del Diablo and Sierra de los Bolbones, 1844; Mount Diabolo, 1848; Monte del Diablo (Original Township boundaries) April 17, 1850; Monte Diablo (Township reorganization) October 18, 1852; modern spelling, Mount Diablo, 1850s.

 The earliest name of the mountain was apparently San Juan Bautista (Dalrymple 1790).  In Oct. 1811, Ramón Abella’s diary mentions the peak as Cerro Alto de los Bolbones (‘high hill of the Bolbones’, i.e., the Indians who live at its foot).  The ridge was later designated as Sierra de los Bolbones (or Golgones, and other variants). 

 The name Monte del Diablo ‘devil’s woods’ appears on the Plano topográfico de la Misión de San José about 1824, where there was an Indian rancheria perhaps near a thicket at the approximate site of the present town of Concord. {Pacheco}

 On Aug. 24, 1828, the name was applied to the Monte del Diablo land grant for which Salvio Pacheco had petitioned in 1827.  Mariano Vallejo’s report of 1850 tells the story of a fight between a detachment of soldiers from the San Francisco presidio and the Indians at the foot of the mountain in 1806 {discredited date, actually 1805}.  The appearance of “an unknown personage, decorated with the most extraordinary plumage,” made the soldiers take to their heels, believing the devil had allied himself with the Indians; then and there they applied the present name to the mountain.  This is quite certainly fanciful. 

 Marshin 1850 stated that Vallejo was incorrect in placing the engagement near the mountain and that it had occurred in the vicinity of a thicket of willows near the house of Salvio Pacheco (i.e. near present-day Concord) at a later date. 

 The name was transferred to the peak by non-Spanish explorers who associated “monte” with a mountain and applied the Italian form Monte Diavolo or Diabolo. 

 Belcher (1:119, writing in 1837) calls the range Sierras Bolbones and speaks of “the high range of the Montes Diavolo” on his left (!) as he entered the Sacramento River. 

 The Wilkes expedition of 1841 definitely fixed the name on the lofty mountain peak.  Duflot de Mofras cautiously gives both names in 1844, Monte del Diablo and Sierra de los Bolbones (plan 16). 

 Finally, Frémont and Preuss, on their map of 1848, give the proper latitude and call it Mount Diabolo.  Trask’s and other maps of the early 1850s established the modern spelling, although Monte Diablo is found as late as 1873 (Hoffman). 

 The geographic identity of the range headed by Mount Diablo was recognized by cartographers in Mexican and early American times.  The BGN {Board on Geographic Names} (May 15, 1908) designated the entire range from Carquinez Strait to Antelope Valley in Kern Co. as Diablo Range to distinguish it from the other chains of the coast Ranges.  (In recent years the expression “Mount San Diablo” is sometimes heard.  Diablo post office is listed in 1917.”
