The Lost Cement Mine refers to a reddish lava ledge containing two-thirds pure gold discovered by German prospectors near Owens River headwaters in 1857. You’ll find Dr. Randall successfully mined similar cement ledges at Pumice Flat in 1861, extracting thousands in gold before the Owens Valley Indian War disrupted operations. Archival evidence suggests Kent and McDougall later recovered $350,000-$400,000 from the site through 1877, though its exact location remains unverified. The sections below explore documented expeditions, military records, and geological indicators that continue guiding modern search efforts.

The 1857 Discovery: German Migrants and the Gold-Cemented Ledge
In 1857, when two German migrants became separated from their California-bound wagon train, they inadvertently stumbled upon what would become one of the Sierra Nevada’s most enigmatic mineral deposits.
While resting near a stream in the eastern Sierra Nevada’s Owens River headwaters region, they observed a curb-stone-width ledge of reddish lava rock containing gold lumps. Mineral composition analysis later suggested the ore consisted of two-thirds pure gold cemented within rusty oxidized material.
A curb-stone-width ledge of reddish lava rock revealed gold lumps cemented within rusty oxidized material—two-thirds pure gold.
The discoverers extracted approximately 25 pounds each before concealing the site and creating a crude map. Though mythical interpretations would later obscure the truth, archival records document that two of three original discoverers perished crossing the mountains.
The survivor’s ore sample and location description reached Dr. Randall, initiating systematic prospecting efforts. Dr. Randall led prospectors to the area in 1861, establishing operations on Pumice Flat near what became Whitemans Camp. The site was periodically mined until 1877, though its exact location became increasingly obscured with each passing decade.
Geographic Location and Search Areas in the Sierra Nevada
The geographic parameters established by survivor testimony and subsequent archival documentation point to a concentrated search zone within the eastern Sierra Nevada’s volcanic terrain.
You’ll find the primary search corridor extends from Pumice Flat—eight miles north of Mammoth Canyon—southward through the Owens River headwaters near Mono Lake.
The 1861 prospecting focused on 120 acres of pumice-dominated topography, while the Crestview marker at Highway 395 designates modern reference points.
Alternative theories place the site across Sierra Crest near Devils Postpile, where hidden cave systems and ancient petroglyphs suggest indigenous knowledge of mineral deposits.
The “burnt country” description corresponds with volcanic formations at Deadman Summit’s pumice hills, establishing definable boundaries for systematic exploration within this geologically distinct zone. Doctor Randall and Gid Whiteman dedicated years searching these pumice hills for the elusive red igneous rock formations that marked the original discovery. The legendary vein was supposedly discovered in 1857 by two men who became separated from their traveling group while crossing the Sierra Nevada.
Dr. Randall’s 1861 Expedition and the Rush to Pumice Flat
When a tubercular German prospector stumbled into Millerton mining camp during 1860, Dr. Randall obtained ore samples, detailed maps, and location data that sparked his expedition.
By spring 1861, you’ll find documented records of Randall filing a 160-acre claim at Pumice Flat, eight miles north of Mammoth Canyon near Mono Lake. His prospecting techniques involved systematic inch-by-inch surveying of the quarter-section using cartographic guides.
Mining technology of the era confirmed specimens displayed “half composed of flakes” through Virginia City assays.
Foreman Gid Whiteman commanded eleven men who extracted “several thousand dollars’ worth” from reddish cement ledges. The expedition targeted the region known as the “Burnt Country”, where volcanic terrain near Owens River matched descriptions from the original German prospectors’ crude map. The original discovery in 1857 by two German prospectors established the legend when they found a red lava ledge with gold resembling cement and collected around ten pounds before tragedy struck.
Yet Randall’s public exhibition of gold-rich ore triggered unintended consequences—miners from Monoville and Mammoth City descended upon Pumice Flat, while escalating Owens Valley Indian War tensions ultimately disrupted operations.
The Owens Valley Indian War and Its Impact on Mining Operations
Escalating tensions between Paiute bands and encroaching settlers created operational hazards that forced Randall’s mining crew to abandon Pumice Flat by late 1861. Ranchers’ livestock had invaded traditional Paiute lands since 1859, triggering retaliatory harassment tactics.
Settler encroachment on Paiute territories from 1859 onward generated mounting hostilities that halted Randall’s mining operations at Pumice Flat.
You’ll find military records documenting the March 20, 1862 raid on Ambama Hills, where troops killed eleven Paiutes and destroyed winter provisions. Lieutenant Colonel Evans established Camp Independence on July 4, 1862, employing military strategies that included canyon patrols against ambush-ready warriors.
Tribal negotiations commenced October 6, 1862, when Captain Rowe and Wasson arranged treaty terms requiring hostage exchanges. Despite Paiute war chief Captain George‘s pledges, conflicts persisted through 1863. Captain George disappeared from camp on March 1, 1863, breaking his peace pledge and signaling renewed hostilities.
The Army’s July 1863 escort of 998 Indians to Tejon reservation effectively ended mining disruptions, though casualty estimates reached 200 indigenous deaths. The Owens Lake Massacre occurred in 1865 as part of Captain McLaughlin’s continued campaigns against Paiutes and their allies in the region.
Rediscoveries, Historical Records, and Modern Search Efforts
Following the 1863 military relocations, fragmentary archival evidence suggests the cement mine’s periodic rediscovery and clandestine exploitation. Kent and McDougall allegedly extracted $350,000-$400,000 between the 1860s and 1877, yielding $25,000-$50,000 annually before concealing their operations.
J.W.A. Wright’s 1879 documentation speculated the ledge crossed Sierra Crest near Devils Postpile, though verification remains elusive.
You’ll find Mark Twain referenced these searches in *Roughing It*, transforming legitimate prospecting into treasure lore. Twain described the cement specimen as large as a fist, containing virgin gold that had captivated Mr. Whiteman through thirteen years of searching.
Horace McCoy’s 1940 article claiming map sightings triggered twentieth-century expeditions—all unsuccessful.
The 1980 E Clampus Vitus plaque near Crestview institutionalized this legendary myth, instructing discoverers to notify chapter authorities.
Modern prospectors continue searching Owens River Road corridors, perpetuating California’s most persistent gold legend despite extensive archival ambiguities.
Frequently Asked Questions
What Geological Processes Created the Gold-Cemented Red Lava Rock Formation?
You’ll find this lava formation resulted from volcanic hydrothermal processes depositing gold particles within oxidized igneous matrices during Sierra Nevada’s geological upheaval. The geological processes cemented native gold into porous red volcanic rock through mineral-rich fluid percolation over millions of years.
How Much Gold Was Actually Removed by the Original German Discoverers?
You’ll find the original German discoverers reportedly extracted fifty pounds combined (twenty-five pounds each), though this treasure legend’s historical controversy stems from lacking independent verification—only secondhand accounts and Dr. Randall’s undocumented ore transfer exist.
What Happened to the Crude Map Drawn by the Original Discoverers?
You’ll find the original 1857 map passed to Doctor Randall in 1860, then guided expeditions until 1879. Historical map authenticity remains unverified, as no confirmed survival exists despite modern imaging challenges preventing archival verification of this legendary document.
Why Hasn’t Modern Technology Like Satellite Imaging Located the Mine?
How can satellites pierce geological puzzles when mining lore describes low-contrast reddish cement blending with Sierra volcanic rock? You’re facing dense vegetation, snowpack concealment, atmospheric distortion above 10,000 feet, and deliberate post-1877 obscurement erasing spectral signatures.
Are There Legal Ownership Rights if Someone Discovers the Mine Today?
You’d need to file a valid mining claim with the BLM, complete environmental assessments, and maintain annual fees for legal ownership rights through modern exploration—assuming it’s on unpatented federal land you can legally access.
