Jim Sleeper on Red Hill

 
I was doing research in the files of the Orange County Archives last week for an article about Tustin’s Red Hill for the Jan. 2017 County Connection employee newsletter, when I came across the most informative piece on Red Hill I've ever seen. It was an April 21, 1975 letter from historian Jim Sleeper to Orange County Historical Commission Chairman Wayne Gibson, who must have asked Jim for an overview on the subject. By Jim's standards, this was just a rough collection of notes and thoughts, but by any other standard it's an invaluable look at an important historical landmark. (To say I quoted him extensively in my own article is an understatement.) Anyway, I thought I’d share the text of it here, along with some illustrations I've added, for the benefit of my readers:

Dear Mr. Gibson:

The press of business prevents me from supplying more than a cursory sketch of Red Hill. Suffice it to say that I consider it to be the most significant natural landmark, with the singular exception of Santiago Peak, left in the county. As for community identification, Red Hill is to Tustin what the Spurgeon “clock” is to Santa Ana, or the “plaza” is to Orange.

Physical significance

Standing 347 feet in elevation, the hill itself is roughly 1,000 feet long and perhaps half that distance in width. It is well defined, both by its obvious color as well as its geologic distinctness from the nearby hills. Volcanic in origin, Red Hill houses an impressive number of minerals. Among the most significant are baryta, aluminum, barite, black sulphide of mercury, mercury, cinnabarite and tiemannite. (State Mineral Survey Bulletin 91, 1922.) In addition, the hill was long a source of petrified wood.

Prehistory

Known to the Gabrielinos as Katuktu, the place figured in Indian mythology as a “place of refuge” stemming from its association with early tales of the Great Flood. Data regarding Red Hill’s Indian legends was gathered by John P. Harrington, of the Smithsonian, from survivors of the Juaneno tribe in Capistrano just prior to World War I. (If memory serves me, the name Katuktu was also adopted as the chapter name of the local D.A.R.)  Indian burials and numerous artifacts have been discovered on and around the hill, but to my knowledge, only one serious “dig” (ORA-300) has been made in that area. This was in 1971.

Early designations

Following its Indian name, a variety of titles were applied to the hill. During Spanish times it appears on the Grijalva Diseno of 1801 simply as Las Ranas, a designation apparently supplied by the missionaries. Red hill stood at the head of the Cinega de las Ranas (“Frog Swamp”) which ran from that place to Newport Bay – hence the name “Frog Hill.” During the Mexican period, the site appears on the José Antonio [Yorba] map of 1839 as Serrito de las Ranas. And on the Jose Sepulveda 1841 diseno as Cerrito de las Ranas. Significantly, this is the name which Sepulveda used in his first (but unsuccessful) application for a rancho grant in 1836. When finally issued a year later, the same parcel was designated as the Rancho San Joaquin. In effect, then, Cerrito de las Ranas is the first name for the bulk of what is today called the Irvine Ranch. Other names were applied to the hill with no apparent confusion. Cerro de las Ranas and ultimately Serrito or Cerro Colorado were the most common.

Following American intervention and settlement, the English equivalent of Cerro Colorado was applied in the 1870s. Just as often, it was referred to as “Rattlesnake Hill,” an appellation which persisted until after the turn of the century, and with considerable justification judging from contemporary accounts.

Survey Point

Unquestionably, Red Hill’s greatest significance during the Rancho Period was as this area’s initial survey point. It is the one point in common for the three ranchos making up the Irvine, marking as it does the eastern border of the [Rancho] Santiago de Santa Ana, and the north-south division point of the [Rancho] Lomas de Santiago and the [Rancho] San Joaquin. Apparently, the hill itself was monument enough, for nothing more than a small rock cairn at its top commemorated this all-important base point.

Mining

Despite its several minerals, cinnabar was the one most prized during the sixty-odd years that Red Hill was intermittently worked as a mine. The scarcity of “quicksilver” elsewhere in the state (non-existent elsewhere in the county) made it significant. Consequently, the promise of big profits stimulated numerous attempts. Mission records may disclose an awareness of the mineral (as mentioned in some papers), but this is unconfirmed. The earliest allusion to Red Hill’s potential occurs in Harvey Rice’s Letters from the Pacific Slope (1869). In describing the San Joaquin (Irvine) Ranch, he states that “mines of coal and quicksilver have recently been discovered.”

As to actual mining, the initial attempt seems to have been in 1884 when it was prospected for cinnabar. Until 1893 all attempts were direct operations of the ranch itself. The earliest name applied was the “Rattlesnake Hill Mercury Mine.” An analysis and description of improvement work is described in Bowers’ Tenth Annual Report of the State Mineralogist (1890). In the year or two following this report, the Irvine Co. sank a tunnel 400’ long, another 30’ and one 30’ shaft.

Fairbanks’ Eleventh Annual Report of the State Mineralogist (1893) mentions a tunnel several hundred feet which was run into the hill from the south as was another 100’ long on the north side.
Between 1896-98 the property was leased by Thomas “Shorty” Harris, who worked the mine with a crew from the Santa Clara Coal Mines. This effort resulted in several shafts about 70’ deep.

The first stock promotion of the mine occurred early in 1899 when a ten year lease was taken cut by two Santa Ana men, R. J. Kimball and J.A. Turner. In the course of the next six months they sank two shafts, one to a depth of 80’, another of 30’. Reports indicate that eight men were employed “around the clock,” and that some 50 tons of ore had been extracted. Literature boomed the mine’s assays as running “as high as 80%’ (of mercury-bearing ore), reputedly worth $250-600 per ton. The mine was heralded as exceeding even that of the Almaden in Spain, the richest in the world, which runs only 10%.” In its best veins, Red Hill’s cinnabarite ran possibly to 50%, but overall it was 5% sulphide of mercury – still high for this type of material. Appearantly production did not match the bombast of publicity, however, for correspondence indicates that the Irvine Co. had trouble collecting its $200 annual lease fee.

On Feburary 2, 1907, Red Hill passed [out of] ranch ownership after forty acres in “block 13, Irvine Subdivision” were sold to Felton P. “Frank” Browning.

During World War I, when mercury was at a premium, the mine was worked again, this time by A. W. Sheets under a lease from Browning. A “chalk mine” was also reported on the hill during this period.

In 1927 the mine was revived by a miner named McWaters who leased the property and recovered 120 flasks of mercury (then selling at $120 per flask). McWater’s method was to distill ore from previous tailings in a wood burning retort. His overall “take” was placed at $12,000. A year or two later, a prospector named Secrest took over the mines and built a larger gas retort, though is profits, if any, are unknown.

Reputedly Red Hill was reactivated for the last time during World War II, though I cannot confirm the developers or their output.

Historical Associations

In addition to mining, Red Hill (under one name or another) figured as a landmark skirted by the Portola party (1769), the mission fathers on El Camino Real, the Stockton-Kearny expedition (1847), the Coastline Stage (1866), and the Seeley & Wright Stage Line (1869), which passed either in front or behind the hill depending on the swampy road conditions at the time. During the 1890s, Red Hill was the scene of frequent turkey shoots, and was the first rifle range of Co. L, the local militia, which also staged mock skirmishes here. In 1899 the first heliograph experiment in the county was conducted by Co. L between the top of Red Hill and Huttenlocher’s Opera House in Santa Ana. In 1909 the first flight of a manned aircraft in Orange County, a glider built by Dana Keech and piloted by Ray McTaggert, took off from the top of the hill.

Historical Recognition

On January 8, 1930, the preliminary application for Red Hill as a California landmark was filed by county historian Terry E. Stephenson. Granted, the site was registered as State Historical Landmark #203.

In 1968 the Historical Advisory Committee of the Advance Planning Division of the O.C. Planning Department designated Red Hill as a county landmark. It so appears on the historical site map of 1969 as #57.

Possibly more telling of the hill’s community identification is the fact that a dozen commercial houses in the Tustin area have incorporated “Red Hill” as part of their business name, not to mention its use as a street name, as well as that of a school, a church and even a volunteer fire station.

Conclusion

In my estimation, Red Hill is an important site – geologically, geographically and historically – not only to its immediate community, but to the county as a whole.

Sincerely yours,

James D. Sleeper

Has anyone recently investigated whether the mine tunnels and other workings still exist?

"In 1899 the first heliograph experiment in the county was conducted by Co. L between the top of Red Hill and Huttenlocher’s Opera House in Santa Ana."

I'm interested in the history of heliographs - is there a reference you can point me to for that? I did a quick search in the California Digital Newspaper Collection at https://cdnc.ucr.edu/ and found material on "Red Hill" and "Huttenlocher", but not together in any one article.

Flasher: I assume Jim got his information from early local newspapers like the Santa Ana Blade (of which there are few to none at the CDNC), from Charlie Swanner's book about Company L, or from some other source of Co. L records.

Anonymous: I suspect it's all out there somewhere. State Bureau of Mines? Anyway, I suspect that the mines are closed up tight for insurance reasons, unless they've already been purposely collapsed (for the same reason).

I really don't like to read the research blogs. After working the whole week, I like to read the entertaining and soft blogs. Your writing skills must be good but the topic isn't intrested.
